How do I volunteer for the event?
Volunteers are the life blood of the event and we therefore appreciate any offers to help. We have tasks that include course marking, sweeping, aid station helpers, registration, timing, post race food preparation, clean up and logistics roving. The assistant RD (Angela Shartel) is in charge of assigning and coordinating volunteer assignments. If you would like to help, please click on the Volunteering link on the left side of the website homepage and fill out the information. Angela will then contact you and coordinate task assignments that work for you and the event. Thanks for volunteering.

Why do you have a website, Facebook Page and Twitter account for the event?
The race web site contains all the information you should need to properly prepare for the event. PLEASE take the time to thoroughly review every page of the web site and download applicable documents for you and your crews/pacers/supporters. Facebook and Twitter are used to communicate with other runners to share information like training runs, make requests for pacers, share transportation, coordinate lodging opportunities, etc.

Will there be a live webcast for the race?
Yes, we will use to post runner's times as they pass major aid stations. These times will be delayed some due to poor transmission from remote aid stations and internet connectivity limitations. The link for the live cast will be located on the web site homepage:

Are the Friday, June 5 packet pick up and formal race briefing mandatory?
The formal pre-race briefing is not mandatory but is highly encouraged. If you are unable to attend this briefing, you must sign in and process for the race NO LATER THAN 5:00 am on race morning.

Are the mandatory cutoff times at aid stations strictly enforced?
Yes, the runner must leave the aid station at or before the mandatory cutoff time. This is non-negotiable. Failure to abide by this rule will result in disqualification and will result in the runner being banned from all future San Diego Ultra Slam events.

What type of food and drink will be available at aid stations?
Aid stations will have as a minimum, water, electrolyte drink (Tailwind Nutrition), Clif Shots and Clif Blocs, coke, mountain dew, ginger ale, ice, electrolyte pills, fruit, salty food (eg chips, pretzels), cookies, sandwiches (PB&J), and some candies. Night time aid stations will have hot soup and hot drinks. If you have special needs for your diet (eg, vegan, gluten free, etc), please use your drop bags for your specific replenishment needs. Aspirin, motrin, advil or other medicants are not provided at any aid stations.

What is the average temperature for SD 100?
The SD 100 course covers elevations of 3,000' up to 6,000' and parallels high ridges along the PCT. Typically for this time of year, the average temperature range is from the low 40's to the mid 80's. However, due to the low humidity, exposure on some sections, and the ever possible strong winds, be prepared for near freezing wind chill factors at night and hot day time heat indexes.

Will there be any formal training runs on the course?
There will not be any formal training runs on the course due to permit and liability issues; however, if you would like to post an informal training run or inquire about any future training runs by others, you can post and/or check for this information on the San Diego Trail Running blog.

Can I have more than one pacer at a time?
No, only one pacer is allowed to accompany their runner at a time. Pacers are only allowed to switch out at aid stations. The first location a pacer can join his or her runner is at Penny Pines 2 (mile 56). The pacer must be dropped off at Penny Pines due to limited parking space. Volunteer parking only. If a crew or spectator parks at Penny Pines, their runner faces a penalty or disqualification.

Can I meet my runner at other than crew access aid stations?
No, crews are strictly limited to meeting their runner at crew access aid stations only. Failure to abide by this rule jeopardizes disqualification of the crew's runner. Each runner (non SOLO Division) will be given one Crew/Pacer car windshield pass to allow that one vehicle to park at Crew Access checkpoints. Cars that do not have this pass are unauthorized to park and must carpool with someone who does have a pass. Sunrise 1 and Sunrise 2 have ample parking to park and then carpool.

Are there showers at the finish line?
There is one outdoor shower which uses Lake Cuyamaca pumped water so you can use it to clean off but the water will be cold!

Is there a formal Awards Ceremony?
No, all finishers will receive their finisher's medallion, belt buckle, embroidered finisher's hoodie, finisher's coffee cup and sponsor donated giveaways shortly after crossing the finish line. However, we highly encourage finishers, crews, pacers, and family to stick around at the finish line and enjoy watching others finish. There will be food and refreshments available until the last runner finishes.

If I have to withdraw from the event, can I transfer my entry or roll it over to the following year?
Anyone who notifies the RD on or before May 1 that they desire to withdraw from the race, is entitled to a 50% refund ($120). After that date, all the awards, swag, venue costs, permit fees, etc are obligated; as such, there are no refunds after May 1.

Are treking poles and music headphones allowed on the course?
Treking Poles are not allowed to be used on the first 12.5 miles of the course due to narrow sections of trail and runners not yet being spread out. They are allowed after Chambers 1 aid station. Headphones are allowed but we request you keep the volume low or only use one earbud to allow you to be safe. Night time headphones are highly discouraged for obvious reasons.

Will there be aspirin, ibuprofin, motrin or any other pain relievers at aid stations?
No, Aid stations will not have any of the above pain relievers available to runners. If you carry your own, please be responsible and follow recommended dosages on the bottle. Ibuprofin can be very diuretic and affect your kidneys during strenuous endurance events, so be sure to drink lots of fluids throughout the event to minimize any potential issues with dehydration.

If I am competing in the Solo Division, can any spectators of mine meet me at aid stations just to watch and cheer?
One of the main reasons for the Solo Division is to reduce the number of support and pacer vehicles at crew accessible aid stations. As such, Solo Runners will not be given a Crew/Pacer parking pass: hence, spectators will only be allowed to see their runner at the Start and Finish line if their runner is a Solo competitor.
