Mine started due to financies, we lost our car and had to have someway to get, FOOD and larger items, that we couldn't carry on the city bus. So I bought a Wal-Mart Roadmaster Mnt. Sport sudo MTB. Found a cheap, used childs trailer and converted to a utility trailer. After taking the Roadmaster to the LBS to be adjusted correctly (cost almost as much as the bicycle!!!), I rode and hauled that POS for 8 months. The great thing is that riding it reminded me how MUCH I missed bicycling. So we saved up cash and bought 2 entry level Jamis MTB's, put skinny road tires on them and started to "ride" longer rides. It's 4 miles to the local Wal-Mart and back home to the Apt. with a load of food for the week, it was "tough" but I did it, it was so much easier going, when we got the Jamis MTB's with lower gearing.
We finally joined the local Cycling Club and started riding the "social" rides and from there we just started putting on a little more miles each time. By July 2009, we did our first "multi-day" tour (motel'd), avg. 40+ miles a day for 4 days. So start slow and just keep adding "miles", each time, it will come to you, ENJOY!!
