Just discovered that Pinterest has an OWS board - here - great photos, quotes, links to resources. Not exactly marathon swimming, but fun nevertheless.
In fact I created an MSF Pinterest Board here. But I only started it it about 6 weeks ago, and hadn't gotten around to filling it out much or advertising it to you guys. I'm not even certain I started it correctly. Most of the initial images are therefore taken from the MSF forum and my blog or Flickr.
I dislike almost all Pinterest swimming boards as they are so boringly predictable and repetitious: Look how much I eat, oh my god I smell of chlorine, my coach is so cruel. It looks every one is curated by 14 year olds.
Your board is way cool, no triathlete stuff like the other one. Love the lamprey. My board (if I had one) would include a pic of a ramora to represent the one(s) that keeps trying to attach to my leg. Trying to scare that sucker (ha-ha) off really gets the heart-rate up and must look a fright to the people on shore.
