WATCH LIVE: Eli Tomac goes for third straight Pro Motocross win at Thunder Valley (2 p.m. ET, Live Extra)


Today the Lucas Oil Pro Motocross Championship heads into the mountains of Colorado with a visit to Thunder Valley Motocross Park for the third round of the season.

Live coverage from Thunder Valley gets underway with the pre-race show at 2 p.m. ET, streaming online exclusively on NBC Sports Live Extra and All four motos will then stream live immediately after, starting with first motos at 3 p.m. ET and then second motos at 5 p.m. ET. Second motos will also air tonight on NBCSN at 8 p.m. ET.

The bad news for the rest of the the field: four motos into the 2015 season, Eli Tomac remains undefeated in the 450 Class. The even worse news: today’s round is in Tomac’s home state.

The defining element of Thunder Valley is the high altitude present in the Colorado mountains. As a result, bikes lose horsepower – which is much-needed for the track’s uphill start – and riders can quickly feel drained if they aren’t used to the thin air.

Fortunately for Tomac, he’ll have a home-field advantage because he lives in Colorado and has experience dealing with the altitude. Even with the presence of former champions Ryan Dungey and Ken Roczen, Tomac looks like the favorite to win his third straight race, especially after being the fastest qualifier in practice today, but anything could happen.

In the 250 Class, Jeremy Martin is looking to bounce back from a troublesome day last week at Glen Helen. The defending 250MX champion had trouble getting his bike started in the first moto and then went down early in the second moto. Both times, he had to start the race from the back of the pack but did well to charge through the field for 6-5 moto finishes and salvage a lot of valuable points.

Marvin Musquin, who is in search of his first career 250MX championship, was able to take advantage of Martin’s misfortunes last week and sweep both motos. Yet to finish worse than second in any moto this year, Musquin enters today with a 19 point lead over Martin and will try to build on his early-season success.
