Free Wednesday Swims all Summer!

This is really where the idea for the Clackamas Cove Triathlon all began, and is an excellent opportunity to get in some Open Water Swim Time with other triathletes.  In the 2014 season, we saw as many as 70 swimmers on a Wednesday night.  Here are the details:


Wednesday nights starting in late-May through the early Fall.  Suit up at 6:15pm, Swim at 6:30pm.  First lap is done by 7:15pm, and some will swim til dark.  There often is a smaller group of stronger swimmers that meet at 5:30pm.

The first lap (800-900m) will regroup at the turns. Laps thereafter are on the buddy system.  At least half of the swimmers do one lap.  Newbies welcome!


Adjacent River Water Temperature in Celcius.  (Add 3 degrees F for Cove temperature.)


Close to I-205 and Oregon City exit 9. See here for a map.



Free. Park at the end of the bike bath on Main Street, and walk 50 yards North on bike path to a small jetty on the Clackamas Cove. Entry into the water is gravel, but there is no glass or debris. This area is not supervised, and we wouldn’t suggest leaving your fancy tri-bike on the roof of your car.  There are no facilities or lifeguards, although the Clackamas Sheriff department keeps a boat house here.


Full wetsuits are recommended. It’s clean, calm, and cooler than Klineline in Vancouver. This an old rock quarry with an inlet to the Clackamas River. There is no perceptible current.

Is this the course of the Clackamas Cove Triathlon?

The race will start in the Cove, then head down the Clackamas River.  There will be a few Wednesday nights this summer where the tide is right to enjoy the race course through the spillway.  You can see the video here!

When does this training series end?

In early Fall, when the water gets below 58, usually people want to call it quits.   Historically, that’s been in early October.

Can I race the Triathlon at the Cove?

Sure!  The 2015 Clackamas Cove Triathlon is on June 21st.  You can register here to volunteer or race!


Disclaimer: Swimming with others in open water is a wise choice because OWS can be dangerous. You are responsible for your own safety, which includes knowing the limits of your swimming skill, endurance, and equipment.
