I went swimming today in Lake Sammamish. I don't usually swim much perhaps because I don't like pools all that much and I can only swim outdoors for a couple of months here in Seattle. I drove towards the Microsoft campus in Redmond on Route 520, then headed south along the lake. I found a nice secluded place near a public park and swam for about 15 minutes. Not much, but I wasn't planning on working out severely today :-). Before I went, I checked to make sure that the Garmin Forerunner is waterproof - it is, but only up to a 1 meter depth. The reading came out OK, as you can see from the map. I zoomed out on gpsvisualizer.com to get a better sense of exactly where I was along the lake.
