Personal Support Vehicles
All personal support vehicles must register with us and agree to provide support to riders in the area your rider is riding. Leap Frog off shoulder support only. No direct follow, no vehicular hand-off’s.  All riders and support vehicles must remember this is an endurance challenge, not a race.

Personal Support Vehicles are allowed but must register at check in.

SAG-Vehicles:  All SAG Vehicles & All Personal Support Vehicles  must register with us.  You must provide the vehicle, proof of insurance, sign a liability release.

Leap Frog support only. Direct follow and vehicle handoffs are not allowed. All riders, crews, and event staff must comply with the California Vehicle Code and any related rules imposed by the event organizer or the California Department of Transportation. Failure to comply will result in DNF or DQ, or no volunteer credit, and/or a citation from law enforcement.

Weather Conditions Our new courses and venue avoids the big wind and sand blowing areas of past years.

Weather must be considered as you plan and prepare for SIDD. Desert weather can vary and be sporadic. Cold: expect in the low 40’s at sun rise, expect wind and be prepared to deal with blowing sand. It will cool down just before sunrise and rapidly warm up after sunrise. Daytime temps can reach into the 80’s. Please take weather planning serious.

Lights. All riders must have and use lights that are considered legal for night riding.

Aid Stations. Our Aid Stations will have water, mostly packaged snacks, fresh fruit, Baked Goods, Hammer and Spiz Products, Peanut Butter and Jelly sandwiches with soda’s. Adobo Velo is providing hot dinner at mile 200. It is important that endurance cyclists train and compete using the same nutritional fuels. We ask you provide and carry your essential calories and electrolytes.
