Bikes

One of my concerns when training for my first triathlon was would my bike be suitable... I was riding a slightly modified Charge Duster, which after a year of commuting now had semi-slick tyres, higher gear ratio (front large cog up from 42T to 48T) and bar ends to help climbing.

I needn't have worried... my first Tri was a sprint, and there were around 10 other mountain bikes... and half of them still had full off road tyres.  This first triathlon showed me that it really didn't matter what bike you road.

For my standard distance race, there were only two other mountain bikes (that I noticed), however I overtook a lot of road bikes during the event.  If there is a lesson, it's that the training is more important than the bike
