Hi Rita - thanks for your great review - be happy to get some more private feedback regarding why you gave us the bad 2/5 rating on 'swag' - although sustainability wise we're not sure RaceCheck should ask that question in this way!

Il m’a manqué du temps pour finir la course. Je dois préciser que c’était la première fois que je participais à une course de natation. J’ai commencé à nager très récemment.

It was amazing—the scenery, the water, but most of all the team. They made us feel safe at all times, and whenever doubts crept in, they were there with words of encouragement. Whether it was a competition or an adventure swim, like the one we did, everyone was welcome. A huge th...
