Thunder Ridge MX Park

Thunder Ridge MX Park in Reliance, South Dakota sits just off I-90 at Exit 248 with three tracks: a long, wide main track built on real natural-terrain elevation, a supercross track for technical work, and a peewee track for the youngest riders.

The elevation is the surprise. South Dakota gets pegged as flat-state riding, but Thunder Ridge sits on real topography, and the main track uses it for lap variety you won't find on pancake-flat layouts. The wide design opens up passing lines and keeps turn entries from bottlenecking.

A 30-bike starting gate handles real multi-class race days, not just casual practice starts, and the schedule carries actual championship races. The supercross track adds a second discipline on the same property, something most regional South Dakota tracks don't offer.

Overnight camping with an on-site pond makes longer stays cheap and easy, and a concession stand covers food and drinks on race days.

For riders in Reliance, Kennebec, Chamberlain, Pierre, Mitchell, and across central South Dakota's I-90 corridor, Thunder Ridge is the closest multi-track motocross park. Sioux Falls and Rapid City riders traveling I-90 stop in from both directions; Exit 248 makes it an easy pull-off. (605) 730-1338.
