Sorry to be a nuisance but I'm trying to organise my fitness regime. When I can't get into the hills I try to do a daily walk(on the level) of about 4 to 4.5 miles. Using one of these app things on my mobile phone suggests that I can do an average speed over that distance of about 3.3mph.
Would any fitness experts care to comment and/or advise? Is that a reasonable distance/speed for two or three days a week?
