Tomac, a native of Cortez, Colo., feels like he’ll have an edge on the rest of the 250cc Motocross field at this Saturday’s Thunder Valley National because he’s used to riding motos in the thin air.Eli Tomac (GEICO Honda CRF250R Motocross) says: “It’s going to be nice to race in cooler temperatures and dry air. It’s going to be easier for me physically, because I live there. Plus, I really want to be there for the Colorado fans.”Tomac said he knows he’ll be under the spotlight more than normal because this is as close to a hometown Motocross race as it gets for him.Eli Tomac says: “My brother is trying to make it in and I’ll have some other friends in too. Having that kind of support at a race gives you an extra kick.”Tomac currently sits fourth in the 250cc class standings, and is only eight points behind third-place rider Blake Baggett.Teammate Justin Barcia, the reigning Supercross East Lites champion, has been fighting a case of mono the last few weeks. Despite his weakened condition, he still managed to gut out a podium finish last week in Budds Creek, Md., and is anticipating nothing less at Thunder Valley.Justin Barcia (GEICO Honda CRF250R Motocross) says: “I’ll be all right. I’ve raced there a couple of times before. The track suits my style real well and the bike has just been awesome lately. I just have to make sure I rest up during the week so I can show up fresh and ready to put on a good show.”Barcia is fifth in 250cc points, 20 behind Tomac.GEICO Honda’s third rider, newcomer Lance Vincent, says he’s looking forward to a healthy dose of mountain air as well.Lance Vincent (GEICO Honda CRF250R Motocross) says: “I’m not going to have to deal with the humidity or crossing-the-United-States travel stuff that I’ve seen so far. I’m sure I’m going to have a higher energy level and really be able to keep learning and pushing forward.”Practice at Thunder Valley gets under way at 8:30 a.m. MDT on Saturday.
