There are so many variables however that the most fun I find is keeping a journal and try to beat your own best times on the same route. Running down a thirty something and a fortysomething on my 30 mile loop this morning was also quite enjoyable. Yesterdays 40 mile ride in 100 degree heat was way off my PB. So I guess I am in the opposite camp. I love my cycle computer and my heart rate monitor and my training log. I get to compete with myself and thats what's fun for me anyhow...knit two pearl one...thats what my gramma was always saying..I know what knitting is but what the @#$%^& is pearling?
