I competed in my first triathlon this year at Seaford.
The organisers and the support staff were the most fantastic people! From the guy who tied my shoelaces just before the cycle start line, to the young girl cheering us through to the finish line, these people were helpful, supportive, friendly and soooo happy! It is down to them that I am going to come back again next year! Please pass on my thanks & gratitude.x
I just wanted to take a few minutes to thank you
And all the staff for the wonderful event. It was my first Triathlon and i was very nervous. I have to say that I was so touched by the encouragements, dedication, professionalism and kindness of the people over there. It was just awesome, fun and unforgettable! I will definitely do it again next year and bring some friends and family. That was just perfect! Thank you,
Just wanted to say how extremely impressed
I was on the organisation of the South Coast Triathlon. Particularly impressed with the compere at the finish line who managed to announce names of competitors as they came through the finish and also where they came from, such a personal touch. I really don't know how he did it, with 3 races going on and also a relay.
