Packet Pickup
Packet pickup will be held on Friday, February 13, 4:00pm — 7:00pm at Sports Basement Redwood City, 202 Walnut St., Redwood City, CA, 94063. The race packet contains the race bib, swim cap, helmet and bike stickers, etc.
We strongly encourage you to pick up your packet on Friday to avoid lines but will also hold race-day packet pickup from 7am - 11am at the race venue in case you are unable to. Additionally, racers get 20% off Sports Basement purchases during packet pickup hours!
Please note that you cannot pick up packets for other racers as we are required to collect wet-signatures for our waivers. Minors must be accompanied by a parent/legal guardian at packet pick-up, or submit a scanned copy of their wet-signed waiver to treeathlon@gmail.com before race day.
AWARDS
We will have prizes for the top 3 in each age category (see FAQ for more info). Our formal awards ceremony will be at 2:30 PM on race day. If you cannot attend the ceremony, you can pick up your awards at the awards table near the finish. Important: We will not mail any awards - you must attend the awards ceremony or pick them up at the table near the finish after the race.
GEAR AND DUATHLON OPTION
Please expect the swim to be wetsuit-mandatory. If ambient and water temperatures fall below USAT thresholds, the swim portion will be converted into a 2 km run (duathlon), starting at the swim entry as indicated on the course maps. Please ensure that the ends of your handlebars are sealed to reduce the risk of injury (e.g., with bar-end plugs). For additional gear advice, please refer to our FAQ.
Martin from TCMTriSquad has wetsuits available to rent for Stanford Treeathlon participants, but will need to coordinate your sizing in advance. To reserve a wetsuit please email tricoachmartin@gmail.com. Martin will be at the race during packet pickup or you can get the wetsuit shipped to you prior. He will also have racebelts, locklaces, goggles, thermal caps and other triathlon supplies. Check out his website to see information about wetsuit rentals at: www.tcmtrisquad.com/wetsuits.
DIRECTIONS and Parking
