Join Roz by pledging to walk/cycle more and drive less. Roz will take an average of 10,000 oarstrokes each day over the roughly 100 days it will take her to complete Stage 2. Match Roz one step for one stroke, each day. Ten thousand steps is about 6 miles or 2 hours of walking. It may seem like a lot, but this includes steps taken around the house, to work, to the loo or to the refrigerator.
