Just some cycling around dropping George off at nursery and various errands. Some people try and completely rest, which to them means feet off the ground. I think some activity is good as it I feel it opens up blood flow to the muscles and delivers the building blocks for repair/adaptation. I'm not sure if this has been looked into.
Everyone in Hawaii wears the fancy swim skins for the swim. I still haven't got one - had a look on the internet, a little prohibitive price wise. In the early days (1970's) everyone did the whole event in swimming trunks - they were a tougher breed.
