“Thank you to the awesome team for organising a wonderful event. My daughter had a great time completing her first tri ever and I am so pleased she did for TRISudbury. The group is just fantastic, so supportive, friendly and driven! I also enjoyed doing the tri today and have fallen back in love with tris after a long break from them.”
