Come and join in the fun of one of the best collegiate triathlons in Northern California. The race is a 600m open-water swim, a 20km bike, and a 5k run. Come join the fun!
There are two separate races taking place on March 5th this year. The Stanford Draft Legal Triathlon for Collegiate and Elite athletes will start at 7:00am. The Classic Stanford Treeathlon, a non-draft legal race, will start at 11:00 am. In each race, we have two categories of waves, men's and women's. While the categories are binary, we recognize that not all people fit within that.
Registration for the Draft Legal event is a separate registration link. Please check the race website for updates.
You must be 16 years old (or USAT Age16) to participate in this race.
Please be sure to check the race website for packet pickup information and schedule changes. Answers to frequently asked questions (water temps, equipment, etc.) can be found here: http://www.stanfordtreeathlon.com/faqs.
