Welcome to the 30th running of the Woodside Trail Run in Huddart and Wunderlich Parks. This classic Pacific Coast Trail Runs event is known for the best trails in the bay area. The Start and Finish Line are at Huddart Park off HWY 280 in San Mateo County and follows the trails through Kings Mountain and Bear Gulch. For those of you running the 35K & 50K you will experience Wunderlich Park also.  All entrants will enjoy plenty of single-track trails under the canopy of towering redwoods and other local growth. This is a magical trail run on soft dirt trails, alongside lush ferns and a green landscape leaving you breathless with the desire to return soon after your finish. 

The Half Marathon will replace the 17K for 2023 and future years. All courses have been revamped for 2023.

STRAVA LINKS: Due to ongoing deforestation projects in both parks, maps and courses are subject to change. Please refer back for any updates. Please also note that Strava course mapping tools always are shorter in distance than all other digital map making apps we have used. The original course was measured using a handheld  "single wheel" which is walked slowly on the dirt for accuracy. The Woodside Trail Run 50K has always been under 30 miles before this year. The new course is more than 30 miles and less than 31.1 miles. Might have you spin a quick look in around the start area to get you to the distance. We hope to have an all-inclusive map with turns, elevation charts, and aid stations on it. Stay Tuned. For now please find the aid stations below and the elevation charts you can find by clicking on the STRAVA links below.
