Training for a triathlon can be expensive.
If you’re just getting started in the sport, certain items can be more costly than some of the other events in which you may have participated. Entry fees are substantially more than a running event, but there’s more overhead involved in putting on a triathlon. Additionally, cycling and swimming equipment with bikes and wetsuits can be pricey.
However, don’t let cost be an excuse for lack of participation. If you can get involved in a local training group, there’s a tremendous wealth of people willing to loan or sell used gear. Personally, I’d rather let someone use gear that I have to participate as opposed to someone not participating at all.
Additionally, there's a great market for the sale of used equipment via the web.
