The UltraSwim #15 Greece will be one of the best, if not the best event, I ever attended. The staff, volunteers, kayak support, prompt customer service support - EVERYTHING, was first class all the way. If anyone is looking for a life changing event, please look into participating at one the Ultraswim events. It will be one of the most memorable events you will ever attend. I am so grateful to have attended. Thank you, Ultraswim!

Greece #15 was my first Ultraswim and it won’t be my last. Organization was excellent - super transport support, amazing location, superb guidance pre race and during (kayaks). The swims were beautiful, and the community at Ultraswim is very welcoming. I highly recommend this rac...

5 star all around. What a fantastic event. Well-run and meticulously planned from start to finish. I have never felt safer during a swim which was done as to feel supportive but not intrusive or "cheating" I cannot praise the volunteers and staff enough.

Having participated in a variety of different sporting events around the world and being very conscious of event organisation and logistics, I can honestly say that this event was one of the most professionally run events I've had the pleasure of participating in. Admittedly, the perfect weather conditions added substantially to the enjoyment of the event but I'm confident that, even if the weather had been patchy, the UltraSwim team would have handled it well. An additional accolade would be the friendliness and helpfulness of the organising team - none of the officiousness which so often accompanies the organisation of events such as these. Well done, guys!

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!
