NEW THIS YEAR!
One hour early start for runners over 60!
Runners over the age of 60 will be allowed to start 1 hour early. However, the aid stations will open at the usual times, so runners taking advantage of this option should be prepared to self-support until the Cuyamaca Peak aid station. More details in the 2025 Racebook when posted.
Scotty Mills Scholarships!
Scott Mills is the former long time RD for San Diego 100 and has fostered the running community in San Diego for years. This year, we will be awarding up to 2 free entries for folks who best demonstrate Scotty's defining trait of giving back to their community, running or otherwise. If interested, please prepare a 2 to 3 paragraph write up of why you or someone else is deserving of a free entry. Send entries to us at sandiego100rd@gmail.com. Please get these in no later than December 28.
10% Discount for Active Military and First Responders!
We appreciate your service! Please contact us via e-mail for a discount code if you qualify. If you are not active military or first responder and you try to claim a discount, just remember that stolen valor is bad karma.
Improved internal cutoffs!
With the new course last year, we found that some of the later cutoffs were a bit tight, so we will be stealing some time from the early cutoffs to give folks more time later in the race. Overall cutoff remains the same at 32 hours!
Higher entry fee!
Oops, we shouldn't be so excited about that one. It is definitely a bummer. Unfortunately, Cal Fire and the California State Park System, in all of their wisdom, are requiring us to have a private ambulance on standby for the entire length of the race as a condition of permitting. This is very expensive, so unfortunately, we have had to bump up our prices a bit to accommodate that requirement. Hopefully next year, they will have a different policy, and we can go back to our old entry fee. We appreciate your understanding and hope you will find that mile for mile we are still one of the best values for an ultrarace out there.
