Round 5 of the 2008 AMA motocross championship will be held under lights at Thunder Valley. The altitude at Thunder Valley causes the bikes to run with less power which in turn increases the running temperature of the bikes due to the riders trying to make them run at race speed. Riders must also adjust to the thin air prior to racing.

This will be only the fourth time the gate has dropped for an AMA Motocross at Thunder Valley. The first AMA Motocross race was held at Thunder Valley on July 24, 2005, with Ricky Carmichael winning on a Suzuki. Ricky Carmichael won the first two races at Thunder Valley, with James Stewart breaking through with his only win for last season.
