Thanks guys. I guess I'll keep off the running for a bit, but running in water doesn't sound intriguing, especially if you can fit four times as much work into the time period.
Are there many classes for this kind of thing or do you just go down to any pool and ignore any quizzical looks that you get? If the latter is the case, then do you run in the shallow end, when water is at waist height or in deeper water?
