The Dirt Devil Grand Slam is San Diego’s hottest new running race series. Consisting of distances 5K, 10K, 15K and half marathon the Dirt Devil Trail Running Race Series has something for everyone. The races are held throughout San Diego County on beautiful nature trails. Locations include Mission Trails Regional Park and San Dieguito River Park. All races provide goodie bags for all entrants as well as finishing medals for everyone. Prizes are awarded to male and female 1st-3rd place finishers.

The Dirt Devil Trail Running Series begins in January with a flat and fast (by trail standards) 5K at Mission Trails Park. The second race is held in March at Mission Trails Park and includes both the 5K and 10K distances. The 10K distance is more challenging and includes single track, river crossings and hills. In August the series is back offering a 5K, 10k and challenging but unique 15K distance at Mission Trails Park. For runners that complete the 5K in January, 10K in March and the 15K in August there is a chance to earn the “Grand Slam” medal in October. October offers The Dirt Devil Half Marathon which consists of fire road, nature trail and single track trail at San Dieguito River Park. All runners are welcome with finishing medals for all. However only those runners that have ran all four distances will earn the coveted “Grand Slam” Dirt Devil medal.
