Short reps

I took advantage of British Summer Time to go out in the late evening for a short rep session in the industrial estate - thought I would aim for 12x80m and go up to 20 if I felt OK. When I started to get bored standing around after the first couple I reduced the turnaround from 60 to 55 seconds, to save a valuable minute (or more) and make the session a bit tougher. Felt fine after 12 so continued, although the session was interrupted after the 13th rep when a passing dog-walker stopped briefly to chat about what I was doing, as he had done some middle distance in the past. The 19th and 20th reps were probably the slowest. No hamstring problems, calf a bit tight towards the end.
