For all you multi-sport Lizards, the Portland Tri Club does group open water swims during the summer months at Clackemette cove on Wednesday evenings. The water there is pretty cold still but some folks have started swimming at Vancouver Lake on Thursday nights at 6:00 until the Cove warms up. The water there is warmer than the Cove and fine with a wetsuit. While it is an unofficial activity and not strictly club supported, all are welcome and there is often a safety kayak there as well.
Thursday nights don't work well for me but Wednesdays do so I have been been doing a swim there on Wednesdays. I understand that starting this week the TNT tri club will be there on Wednesday's as well.
So if any TRL folks are interested, I would love to have more company. (Safety in numbers you know).
