sorry - I was offline for 2 days! Actually I find I don't run as far as I used to before I was cycling. I was running 3 miles just to work out the dogs but I've cut back to 2 miles. The dogs haven't seemed to notice! If I didn't have the dogs I'd probably be running 6-9 miles coz that's the distance I prefer. Since I"m a commuter during the week there are days when it's tough to get myself motivated to run after riding 6 miles up the mountain in 21 mph headwinds (like last night ) or in the winter when it's cold and dark by the time I get home - but I"m working on that!
