Here is a primer for the 24 at Daytona this weekend (also known as the Rolex 24 Daytona in deference to the provider of the traditional* prize of a watch to class winners).

Where can I watch/listen to it?

Motors TV and Speed have TV coverage for Europe and the USA respectively. Magnus Racing (one of the GT teams, running car #4) will have an on-board camera accessible via the internet all race. Please consult your TV listings if you live elsewhere and post if you are in a position to augment or correct my information.

Where is it?

The race is held at a tri-oval with infield section called the Daytona International Speedway, in Florida, USA. It is 5 hours behind GMT. The track is 3.56 miles long, with very fast corners (aided by the 31-degree banking) and somewhat trickier (but still fast) final sector.

How old is it?

The 24 at Daytona celebrates its 50th birthday this year, having run a race every year since 1962. It has "only" been 24 hours long since 1967, which is still long enough to be considered one of the three races in the Triple Crown of endurance racing (albeit Petit Le Mans is sometimes substituted for it).

Points situation?

It's the first race of the Grand-Am season, so nobody has any points at the moment. Many of the entries have no intention of completing the whole season, but some will complete the 13-race calendar. For those doing so, the points on offer go from 35 for the winner to 1 for 30th place. Only finishing positions score points.

Who and what is in it?

The entry list is divided into prototypes (which are all a Grand-Am specific class called Daytona Prototypes) and GT cars (which are also a Grand-Am specific class, similar to GT3s in performance level). It's a very long list, so I will simply provide a link to the full list and highlight some names who may do well.

Prototypes

#01 Chip Ganassi Racing with Felix Sabates, BMW-Riley (Hand, Pruett, Rahal, Rojas)
#02 Chip Ganassi Racing with Felix Sabates, BMW-Riley (Dixon, D Franchitti, McMurray, Montoya)

Chip Ganassi has raced at Daytona for 7 years, with Scott Pruett having been there since the beginning. It won the 24-hour race last year as well as in 2007 and has three championships under its belt in this series. It is difficult to find any weak link in this team, though Corvette is providing strong competition.

#2 Starworks Motorsport, Ford-Riley (Hunter-Reay, Kanaan, M Potolicchio, Scala, Viso)
#8 Starworks Motorsport, Ford-Riley (Dalziel, Luhr, McNish, Popow, E Potolicchio)

Starworks is running a pair of grandfathered cars this year, in contrast to the likes of SunTrust (car #10) who have a 2012-spec car. In testing, the #2 had the fastest grandfathered car in the "Roar Before the 24" test. Allan McNish of Audi is in #8, while the #2 car is full of Indycar stars.

Sadly the #2 StarWorks has since been withdrawn.

#10 SunTrust, Corvette DP (Taylor, Angelelli, Briscoe)

By some margin the fastest prototype overall (though not the holder of its fastest lap), SunTrust has clearly learned the Daytona circuit well. Keep a close eye on SunTrust as it is arguably the strongest contender for the overall win.

#60 Michael Shank Racing with Curb-Agajanian, Ford-Riley (Allmedinger, Negri, Pew, Wilson)

Like the #2 Starworks, this car is full of Indycar experts. Michael Shank Racing has previously qualified on pole in Daytona, back in 2008.

#76 Krohn Racing, Ford-Lola (Braun, Jonsson, T Krohn, Zonta)

Nic Jonsson turned the fastest lap of the "Roar Before the 24" test, suggesting that Krohn will be extremely quick in qualifying. He and Tracy Krohn teamed up to great effect in the GTE-Am class of ILMC last year, while Ricardo Zonta is an ex-F1 driver.

GT cars

#03 Extreme Speed Motorsports Ferrari 458 (Brown, Cosmo, Sharp, van Overbeek)

It's the first time the Ferrari 458 has been used at Daytona and it is proving to be a very quick car in Daytona configuration. Ed Cosmo produced the fastest GT lap of the final day. Extreme Speed hasn't done Daytona before but it is already a very strong prospect.

#45 Flying Lizard Motorsports with Wright Motorsports, Porsche GT3 (Bergmeister, P Long, Neiman, Rockenfeller)

Last year, Flying Lizard took overall pole and second place in the race with a prototype. In GT they will be with a car they are even more familiar with, making them a big threat for the top positions. Mike Rockenfeller will be familiar to most sportscar fans from his work at Audi. His talents will be complemented by Joerg Bergmeister and Patrick Long, who drove commendably for Flying Lizard in ILMC last year. The weak link is likely to be Seth Neiman, but even so, car #45 should not be lightly discounted.

#48 Paul Miller Racing, Porsche GT3 (Bell, Maarsen, Miller, Wilkins)

Rob Bell impressed enormously at JMW last year and his addition to the squad will help it a lot. The others are experienced at Daytona. Expect car #48 to run quietly under the radar and surprise with a good result at the end of the race.

#51 APR Motorsport, Audi R8 Grand-Am (Baas, Canache, Norman, Pirro, Moltke)

APR Motorsport has two things in its favour; the Audi R8 (as a new car to this category, a surprise could be sprung) and the evergreen skill of Emanuele Pirro. The car will probably run in the back half of the grid most of the time but have some spectacular stints from Pirro to enliven the race.

#55 AF Waltrip, Ferrari 458 (Augas, Kauffman, Pastrana, Waltrip)

European powerhouse AF Corse and Michael Waltrip team up with 24H Le Mans team-mate Rob Kauffman. Expect Rui Augas, who raced well in GTE-Am ILMC last year, to be quick. It is not yet clear how fast Travis Pastrana will be, but this year is mostly a learning experience for the AF Waltrip alliance.

#59 Brumos Racing, Porsche GT3 (Davis, Haywood, Keen, Lieb)

Brumos is a highly experienced squad, with all four of its drivers having done the race in its car last year. They carry the confidence born of winning the Grand-Am championship last year. Marc Lieb is one of the fastest GT drivers in ILMC and Leh Keen is doing very well in GTC. Hurley Haywood is doing his 40th and final Daytona, so it would be good to see him and his team-mates have a great race to remember.

#62 Risi Competizione, Ferrari 458 (Bruni, Fisichella, Matos)
#63 Risi Competizione, Ferrari 458 (Beretta, Bertolini, Vilander)

Risi Competizione hasn't visited Daytona in over a decade, not that anyone would have known from looking from the timesheets. Toni Vilander produced the fastest GT lap of the entire test. The Risis have been slightly inconsistent, but much of this is due to three of its six drivers having never driven in a Daytona race before. By race day, expect both cars to be up there with the best. Each car is only going to use three drivers in a race that normally uses four, but everyone in the squad is experienced either with Daytona or Le Mans' 24-hour races, so fatigue shouldn't pose a significant problem.

#64 TRG, Porsche GT3 (Ardagna, Costobal, Da Guida, Orjuela, Salazar)
#66 TRG, Porsche GT3 (Farnbacher, Keating, Pilet, Simonsen)
#67 TRG, Porsche GT3 (Bertheau, Bleekemolen, Goosens, Henzler, Pumpelly)

The record of TRG is excellent at Daytona. They've put 5 cars into the race, 3 of which are likely to be of particular interest. The #66 TRG has got the core of the old Spyker GT2 team in its driving squad, plus Patrick Pilet from the IMSA Performance Matmut team. This balanced squad should help it do well in the race. The #67 TRG also has a high-quality driver line-up, ranging from Jeroen Bleekemolen (one of the stand-out talents in GTC last year) to Wolf Henzler, who was in a huge variety of GT races last year and did respectably well in all of them. While the #64 TRG probably won't be as quick as either, it does feature ex-F1 racer Eliseo Salazar.

#70 Speedsource, Mazda RX-8 (Bomarito, M Franchitti, Hinchcliffe, Tremblay)

Marino Franchitti knows sportscars well and will be the key to this car's speed. Promising Indycar driver Jamie Hinchcliffe has joined in and the other two drivers are experienced with the Mazda RX-8. They've looked pretty good throughout the "Roar Before the 24" test.

#88 Autohaus Motorsports, Camaro GT.R (Edwards, Marsh, Milner, Taylor)

Autohaus is a strong team that came 2nd in the Grand-Am championship last year. The only car out of those I've highlighted to be using the Camaro GT.R, the balanced line-up is likely to be strong.

#93 Turner Motorsport BMW GT3 (Auberlen, Dalla Lana, Marsal, D Muller, J Muller)
#94 Turner Motorsport BMW GT3 (Auberlen, Dalla Lana, Johnson, Said, Werner)

While there are BMWs in the prototype race, this is the place to look for the drivers who previously competed in the ILMC and ALMS series. There is a lot of talent here. Granted, many of the drivers don't have Daytona experience, but they are all likely to learn the ropes quickly. Also, the Auberlen and Dalla Lana mentions are not typos; in Grand-Am, drivers are allowed to swap cars if entered for both, provided drivers doing so only take points for the first car they drove out of those listed.

* - I say "traditional" but it's only been awarded since 1991, the point where Rolex began the sponsorship.

I spent much of last night live-commenting on the opening round of the Intercontinental Le Mans Cup, the Sebring 12 Hours. It is also the opening round of the American Le Mans Series.

The race proved very exciting but was difficult to follow. To the organisers' credit, there was an attempt to make the series easier to follow than ever and I've heard the ESPN3.com coverage was excellent, at least for some people. However, only viewers in the USA could watch it that way, for international coverage was on a separate stream on americanlemans.com. This was a good idea, except that it appears that interest in the race was severely underestimated.

The official site's video coverage seriously lagged. By halfway through the second hour, it was three minutes behind the action and the stuttering on the audio was so bad I had to mute it. Thankfully two alternative audio streams were available. Not trusting the one hosted at the same site as the stuttering video, I opted for Radio Le Mans.

Radio Le Mans worked well during the afternoon, being smooth and consistent. Then I went to swimming club just before 6 pm GMT (3 1/2 hours into the race). I wasn't around to see it, but apparently there was a point in the action where the only information source available was Twitter. The video, all audio streams and both live timing systems were all down. The audio was back up and running by the time I was home at 7:30 pm GMT (5 1/2 hours into the race) but from then on everything was quite shaky. I had to reset the commentary four times between that point and the end of the race (something which had been unnecessary prior to going out). Even using Twitter was chancy because some people (including some official sources) were following the race using streams of varying timeliness.

Naturally, this was unsatisfactory to the many people watching. Sidepodcast's hour-by-hour visit recording system (known as Heartbeat) demonstrates this vividly. After steadily increasing in views during the hours between the race starting and 18:00 GMT, there is a sharp fall in viewers in the two hours following, probably due to people getting fed up and leaving. Indeed, by 20:00 GMT, the figures are only about twice as high as for the morning commenting, which is the quietest time of day for the blog. Yes, the figures recovered as the night progressed (though ignore midnight onwards because a second event, the Red Bull Crashed Ice event, was being live-commented there later on) but think how many more viewers would have been there if everything had worked correctly.

This is a very widespread problem in motorsport but rarely is it put in such stark relief. I know it's difficult to cater to the multitudes, especially when you have no idea of the volume of those multitudes (it was the first time ESPN had attempted to provide a visual service to international ALMS supporters and it was only the second race of this level the ALMS had attempted to live-stream internationally). Nonetheless, the message is clear.

Improve reliability and the potential rewards are huge.

Low reliability will carry a heavy price.

Much like endurance racing for the teams themselves, really. Aim for the sorts of reliability the GTC class had. Not those of LMP2*...

* - I do not believe I am offering any spoilers by saying that all 8 GTC cars, even the ones that didn't see the flag, completed more than 70% of the race distance (in other words, enough to be classified had this been an LMS race) and only one of the four LMP2 cars did so.

Warning! Long entry alert!

I spent quite a lot of the weekend attempting to find out information about Giancarlo Fisichella's latest adventure. Considering that it was an international sportscar race (link in Italian), this proved surprisingly difficult.

The race was the 6 Ore di Vallelunga (link in Italian), an endurance race slightly longer than a typical Le Mans Series race (because there is no maximum distance) for GT2 and lower. GT2 is the level Giancarlo races at in sportscars and the race is an independent one, so initially my reaction to him being on the entry list was excitement. Especially since, at fewer than 80 miles from Fisico's home district, it would definitely be his home race.

Then I spotted a slight problem. Coverage.

Sportscar racing is challenging to follow at the best of times. Pit stop counts that sometimes enter double figures, safety cars that pick up whoever happens to be convenient, high entry counts leading to multiple simultaneous incidents... At least the multiple classes would be a minimal complication this time. Usually Giancarlo races in ACO-sanctioned events these days, where GT2 is the slowest class, but in Vallelunga GT2 is the fastest permitted class. So winning the class would surely require a race win.*

Usually the way round all this confusion is to load up a live timing screen. By necessity more complex than any single-seater enthusiasts use for F1, the versions supplied by LMS, ALMS and the 24H Le Mans official websites all offer reasonable means to follow what's happening (when they load and update correctly). The Vallelunga organisers... ...didn't.

There was some news available on the official site, but as far as I could tell (with admittedly limited Italian language skills) there was no live timing. Or broadcasting. Which brought me to the second problem.

To a certain extent, it's possible to follow a sportscar race even without live timing if you have a decent commentary team. Having established there was no official version, my next port of call was Radio Le Mans. Having a commentary team I'd grown to enjoy in the past season (covering four different rulesets and three different continents) explain the complexities of this race (under a fifth ruleset) in my native language would be helpful. Alas, they appear to have gone on a well-deserved off-season break from commentating.

Bereft of alternative ideas, I asked my friends for help.  At the Fisichella Forum suggested half-a-dozen possible sites that could be used. One of them worked, and I looked forward to attempting to understand the race using the likely-sounding Italia-Racing.it (and secretly hoping everyone stopped for ice creams mid-race, since I'd just covered that topic in class!).

On Sunday morning, I duly tuned in... ...and heard "although no-one understood, we-were-holding-back-the-flood..." While I usually like that particular Take That song, I didn't think it was a good sign that I was hearing it 3 minutes before the start. Ah well, maybe it's one of those stations that thinks starting and ending 30 seconds the show either side of the flags is slick and efficient use of time.

The Shakira song that followed made me worried.

The Elvis song that started as the race was due to start made me very worried. "Suspicious Mind(s)", even...

By the end of the next song, I was ready to panic. I'd been checking my social networking services while listening to the radio and seen a photo proving the race had started during the song. It was some Italian pop track, but I was past caring who'd sung it as it was now at least 5 minutes into the race. The way the presenter was talking made it clear I shouldn't expect the station to be covering any racing today. Even if a station called Italia-Racing might be expected to do so.

I'd previously checked through the other 5 links I'd been offered and found that they didn't work or were Internet TV sites requiring registration. Checking against the official site, I noticed something buried deep in the qualifying report (link in Italian) - official broadcast rights were with Sky and they were showing it next week (or possibly the week after - by that stage I couldn't be bothered to get the calender out).

The next hour was spent rambling through every Italian internet radio station I could remember or research in case anyone was unofficially broadcasting the race. Highlights included a lovely club cover of Queen's "You Don't Fool Me". But all the synths in the world weren't going to tell me how Giancarlo was doing in his home race...

After scanning through my social networking, blog and fora contacts (and finding a few photos of practise), I concluded that nobody else I knew had any further information on the race. By this point, I elected to take out my frustration in a game of Worms.

An hour later, logging back in hope more than expectation, I searched on Twitter and found Laura Bonetti tweeting about the race in progress! I knew she was at the track, but I'd assumed that her lack of tweets since the start meant that she was concentrating 100% on what was in front of her. I was pleased to be wrong and even more pleased when I read Giancarlo's car was in the lead. That must have been an exciting couple of hours...

So that, eventually, proved to be my one source of live information - a spectator who was generous enough to spend a little time not looking at the cars in order to post little updates. There's a certain excited tension about following a race via short occasional messages - you start imagining everything that could have happened, refresh, decide nothing's happened, refresh a few minutes later... ...and find that everyone's lined up behind a safety car because of someone else going off.

I probably should have seen an omen in that particular tweet. Just over hour prior to the chequered flag, it started raining. Nearly everyone stayed on slicks. It was on this awkward combination that Giancarlo went off-track. Vallelunga doesn't feature the acres of tarmac run-off that adorn the average Tilke-drome, so it ended Giancarlo's race. The classified position of 7th does not show that he and his team-mates  Perrazzini and Cioci had led the majority of the way without much trouble from opponents.

AF Corse still won the race with a different car (the #10 - they'd sent 4 to the race), followed by the pole-sitting #7 Kessell Racing and the #26 Porsche, which was a GT3.

The race was an interesting and sounded quite exciting, but would have been better with a little more... ...something. A bit like my viewing experience of it, really. Hopefully when the organisers turn this event into a 4-race series the coverage will improve.

* - Just don't tell the LMP1 teams at the LMS at Hungary this year that. The fastest of them was beaten by 5 ostensibly slower LMP2s...
