Ice miles, very cold water swimming

Starting this thread as more general than Lesotho Ice Mile. A recent NYT article on it: www.nytimes.com/.../for-swimmers-with-ice-water-in-their-veins-an-event-to-match.html Loneswimmer's blog on cold water swimming: loneswimmer.com/.../ Northwest Kingdom's Kingdom Games, Memphremagog Winter Swimming Festival, March 3-5, 2017: kingdomgames.co/.../ The last two have embedded video links that should be useful.
