“Too”sday ride nights are where we come to grow our skills, find a sense of community and be surrounded by like-minded women who share the love of dirt bikes, growth, and just plain fun.

Thunder Valley offers a private, prepped track ($20 gate fee) + $8 GRT drop-in (without membership)

GRT CO alternates between Leadville MX, Thunder Valley MX, and Dry Lake MX, so be sure to check out our event calendar for the 2023 season schedule.
