Swim Report – October 18, 2014 – Storm Surge Edition

I caught up with Nick on the walk out to L1 from Clark Street, and we knew we were in for a very different kind of swim this morning. A strong and steady wind was already hitting us while we were still 1/4 mile from the lakefront – not a good sign! And when we got to... Read More


Swim Report – October 11, 2014 – Autumn Chops!

Nine of us made it out to L1 just before sunrise. The lake temperature came in at 58F (surface) with a 56.7F reading taken in swim. In a pleasant contrast to last week, we had a rather tolerable 49F air temperature. But the lake itself was a bit of a mess. We had some heavy... Read More

Swim Report – September 27, 2014 – Hints of Summer

Nick, Martin, Renee, and I met out at L1 just in time to catch yet another amazing sunrise. We had some slight chops that made this swim a bit more of a workout than we had planned. But the 63.5F lake temp and 60F air temp was about as ideal as you could get. I hope you got... Read More
