2023 Biltwell 100 Race



Entries for 2023 are sold out.


The Biltwell 100 is designed to be fun, challenging and safe. The 25-mile course we’ve laid out is very Baja like– fast, lightly whooped out and not very rocky or technical. Pits and Start-Finish will be in the same spot as last year, but expect an all new course! Logistically it’s a breeze with only one pit area at the Start-Finish that is easily accessible with motorhomes and non 4×4 vehicles. Spectating can be done anywhere along the race course as long as you stay 150 feet from it. You are encouraged to bring a dirt bike, quad, SXS or buggy and come out and enjoy the surrounding trails before, during and after the race. Camping is “dispersed” and free of charge. This area is BLM land, so all the usual rules apply and we expect you to leave it cleaner than you found it when you leave. There will be award festivities at start/finish area on Saturday night.
