Like the look of what Rab's doing and rather than do cardio indoors whilst on holiday I fancy doing beach sprints. I read about doing these a few years back in Men's health I think. How's the best way of going about this considering the beach is unlikely to be marked out and I'm a terrible judge of distance... Was thinking something like a timed sprint, an appropriate cool down pace and then a rest and repeat.
When they finally stop fcuking around at crewe park, I can do sprints there as it's marked out pretty well for walking/jogging.
Any thoughts on Beach sprints - for the record, I'm assuming I'll be bare foot.
