I've been toying with the idea of adding swimming and biking to my running as crosstraining. The thing that I really like about running is the cost. A couple of pairs of shoes a year, a few race entry fees, some technical apparel and that's about it.
So far I do have a bike. It is however a mountain bike. I have priced out tires for the road and they come pretty cheap in comparison of buying a $700+ road bike. If I am going to ride any kind of mileage I'll have to get those clippy pedals which so far I have priced out at about $150 for shoes and everything. Then I'll have to get those fancy handle bars that make it look like you can take a nap while you are riding. I have know idea how much they'll cost.
I have gone out and bought myself a nice pair of goggles and plan to swim the lake so I'll probably need ear plugs $5.99 no biggy. Plus swimming in the murky waters of Lake St. Clair will be free no membership required.
Why not eh?
