She is a good triathlete, but not strong enough to be a winner. But she is rel good at swim and bike. So took decision to leave out better overall triathletes to use her pace in swim and bike to help Helen J. Simple if controversial.
Not sure if they are swim suits or merely high cut tri suits. I would be surprised if they were the former without any padding.
One of the worst sights in triathlon is following blokes (not drafting!) wearing speedos on the bike leg!!!!
They need to put some sand or something on that greasy bend.
(edit: officially it certainly is not a team sport!)
