wow, a whole thread on cycling and I missed it!

I dont know where to start really..

1) Yes, get a road bike not an MTB if you want to be a triathlete.

2) Get a helmet. Really, get one, and wear it.

3) Only other piece of equipment I wouldnt ride without is cycling shorts. You will get a very sore and painful arse if you ride for any distance without them. Its the padding. Also because they are skin tight they dont catch on the seat when you move around. Loose long trousers are worst of all, they get caught in your gears.

Cycling shoes are great, but you can ride without them. Plenty of people do. A stiff sole is what you want. SPD's are great, but again you can come back to shoes and SPDs at a later date. Id start off with some straps, theyre as cheap as chips and not bad. I rode with them for years.

Make sure the frame is the right size. Cant believe no-one has mentioned that. The wrong size frame can give you back ache or worse.

heart rate monitors, gps and other toys - they are great but just ride the bike and the improvements will come.

Get used to when it goes dark at different times of year. Normally in everyday life we dont care so much. You need to know this because riding without lights is lethal, and probably for you more than the other person.

Finally, stuff the bike in the back of the car and go off somewhere scenic for the day. Take a fiver in a pocket somewhere and stop off for a sandwich and a drink. The scenery, the sense of freedom, exploring and the fresh air are what loving cycling is all about.

Hope you enjoy
