A trail running charity fundraiser in honor of World Water Day. Love trail running? Would you like to experience the gorgeous trails surrounding some of Marin County’s most pristine reservoirs, while simultaneously contributing towards alleviating the global water crisis? If so, we would love to have you as a part of Lag Bon 10K trail run!

Our goal is to raise money and awareness of the need for access to clean and reliable drinking water through our shared passion for trail running. All ticket sales collected in excess of the cost of the event will go directly to the highly effective NGO, Evidence Action.
