Coming February 14, 2015. Grab you sweetie or your best TrailblazerGirl-friends and head to the City by the Bay on Valentine’s Day for the I Left My Heart in San Francisco 10K, Half Marathon. This fun, urban race starts with map indicating where 20 hearts are located throughout the city. Then, in teams of 1 to 5 people, decide the best route to run, walk, skip, or dance to visit 11 hearts for the 10k and 15 hearts for the half marathon. Once you are at a heart, there will be a simple multiple choice question to answer (to prove you found the heart). Make it back to the starting point by the designated time for prizes and raffles. A “heart-felt” urban adventure in a beautiful city!
