So this morning they were swimming the 10 km open water swim. Even in my competitive swimming days, was trying to think how far I swam in our swimming marathon to raise money. 200 lengths I think it was and about 2 or 3 miles maybe. I wonder if I could swim 10 Kms. Just to see if I really could do it. Not in competition you understand just to do it. Can't believe they did it in about 2 hours. Very impressive. As a blind person, I find open water swimming a bit disorienting so will stick to pools and fun swims in lakes or rivers.
