Bannerman’s Island 10K

Inspired by the pioneering efforts of my swim buddies who ventured the 20 miles across Cape Cod Bay this week, today I tested a new swim in the Hudson: Cold Spring to Bannerman’s Island return, a super scenic 10.5K trip timed with the changing current, so you swim north to the island on the waning flood and south on the ebb. This is a destination well known to kayakers, but I am not sure it has been swum before.

Neither direction offers a lot of tidal assistance since the swim is timed around the slack tide. However, I was about 30 minutes late to start this morning so the tide was turning when I was only half way to the island. The island generously offered a tidal shadow, with the tell-tale debris patches, which I hid behind until I had to venture out into the current to get around the island. At a leisurely pace it took a 1hr 40 mins out and 1 hr back. The conditions were calm and great for those of us with cold blood — water temp was 82˚F!
