About the Event

Join us for a 12-week series of races at Lake Merced each Thursday evening between June 4 and August 20. Low-key, fun events, and entry fee is just $2.

Race day registration ONLY, no pre-reg is available. Please note that we have had to increase our entry fees to $2 this year due to rising permit costs. Exact change/small bills are greatly appreciated, please make every effort to do so, and absolutely no coins are accepted.

All races start and finish at the main parking lot at Lake Merced, and races start promptly at 6:30pm. Registration opens at 5:45pm. Course closes at 7:30pm, so if you cannot complete the course in an hour's time, you will be asked to self-time and begin earlier than 6:30pm.

Free parking available at the race start.

Runners will be awarded age division points during the 12-week series, with final awards handed out at the conclusion of the series. Please note that you must race in a minimum of six races to be eligible for an award. Awards will be given three-deep in seven different age divisions, male/female.

Go green! We ask that you re-use both your bib number and safety pins each week!
