Exciting Championship Event Featuring Cash Prizes!
The Marin 10K is a part of the Pacific Association-USA Track & Field Road Grand Prix, guaranteeing an exciting and highly competitive field. Pacific Association athletes (with current USATF card) and club teams are eligible to win cash prizes from a $3000 prize purse. In addition, a male or female 10K winner who breaks the course record will receive a $1000 bonus! And, there is a $250 bonus award to runners 19 and over who set a 10K age-group record in the 19-29, 30-39, and all subsequent standard 5-year age groups on up.

The 10K has a long history, and the course records are fast: 28:45 (Phillemon Hanneck, 1994) and 33:08 (Chelsea Reilly, 2013). Click here for a complete list of winning times over the years, plus all age group course records.

Going Green
Tamalpa Runners is trying to minimize the environmental impact of this event by providing recycling bins at the start/finish area for cardboard, drink containers, etc. Compostable cups will be used at the aid stations. Bring your old running shoes and we will recycle them.

For your safety and the safety of others, runners are requested not to wear headphones during the Races.

Youth Track Races Youth Track Races
The Youth Track Races are held after the conclusion of the 10K and 5K. They are open to all kids age 12 or under. Distances are chosen to be appropriate for each age group, starting with a 50 yard dash for toddlers accompanied by a parent, up to a mile run for the older kids. One $5 entry fee entitles a child to as many events as he or she wishes. It's fun to be part of and fun to watch! A great photo-op, too. All kids get runner numbers, participation ribbons, and other cool souvenirs. Parents can register their kids in advance by mail or online, or right up to the last minute at a special table set up alongside the track.

Volunteers Needed!
Did you know that due to the large number of participants and the complexity of the course, the Memorial Day Races requires over 150 volunteers? If you're not planning to run, please consider volunteering a couple of hours on Memorial Day, or on the days just before or after, to help make it happen. If you can help on race day, please e-mail Race Director Kees Tuinzing at
, or call him at 415-686-0703. Please send him your name, mailing address, phone number, and your preference for what job you’d like, if any. All volunteers will receive race shirts, and will be welcomed at check-in with coffee and muffins. Teenagers are encouraged to volunteer, too, and can receive community service credit for their schools if they do.
