I do 25.6 mph on my fixie (average) over the local mountains (well hills

) and back along an old railway path. I cycle pass Knockhill raceway each day, do you know it? I do a 20 mile round trip per day. I do the 20 mph thing with her on an old MTB. (specialised rockhopper)

. Well, yesterday it was 18.4 mph. Sounds like I am showing off but I can assure you while that is easy, to a degree, running is NOT. I busted my fixie one day and had forgotten my pack with spanners etc in it so had to run home the final 4 miles with my bike on my back. NOW THAT DAMN NEAR KILLED ME. Anyone who runs is far fitter, in my opinion, than a person who cycles. I guess that is why runners make good triathletes.
One thing I have learned from talking to many cyclists is that they have this super fast speed which they achieved once, on a mild day, with a low wind resistance etc etc and often downhill. They could probably do my course in half the time.

. If they really were this good though then you would never have heard of Lance Armstrong. I know a couple of runners, however, who have done the marathon thing and they and all their pals go out in all weathers and with sprained this and broken that and run 10-15 mph for fun. Suddenly, doing 20 mph on a bike is not so impressive eh?
I do ride without clips, yes. I was warned against them by the shop when I started to ride a fixed gear and now just find it more comfortable. I have tried those racing shoes but they hurt as they keep your foot straight all the time. I was thinking next pay day I might get some straps/clips though as, by all accounts, it will make me go faster as you use them to pull your foot through the second 180 degrees of rotation on a fixie.
