Several of our new female club members have had questions about what to wear for their first tri. With the season beginning, now is a good time to get prepared.
You should wear a bra under your tri suit or running vest. You should be running in a well fitted and supportive sports bra, not a tight crop top (see links below). The same one that you wear running is fine, just make sure any removable padding is removed so you are not any soggier than necessary. It might feel a bit odd at first to be in a wet bra on the bike but it will be long forgotten by the time you get on the run.
