I have accidentally been getting fit recently. My wife is training for the Edinburgh Moon Walk (a women's charity power walk of 26 miles overnight on the marathon route) and for the last 4 weeks I have been accompanying her on her training walks. Last week we did 6 miles, 6 miles and 8 miles and the distances will be increasing as the event approaches. At the moment the distances are quite short compared to what we've done before but we're doing them at a very fast pace. As a consequency of my increased exercise I've lost an inch off my waist measurement in 4 weeks. It will be interesting to see what happens over the next 8 weeks.
