I cycle daily, but do no "proper" sport, so have decided to run for an hour 4-5 days a week. First try today-was actually wonderful (was dreading it to start with), breathing worked well, pace was great, no stitches, didn't walk, and ended up doing 6 miles in the hour. If I keep this up when will I start svelting? I want to look like an exercise lady, not a lady that is puffing off the pounds!!
