We are a leading UK event organiser based in Penshurst, Kent and operating across the UK, France and Ireland.


As my first ever triathlon I really, really, really enjoyed this! I loved being spurred on to get cycling, swimming and running. Having not competed in a "running race" since I was perhaps 13 - I really enjoyed the competitive edge too! All in all a great day and a great way to get me off the sofa and outside getting fresh air and exercise!


Just wanted to say a huge well done today. Firstly and above everything else the marshalls and staff were all amazing, so professional, so friendly and so encouraging and supportive. The course was great and all the obstacles were fun and achievable.  I think you thought of everything, the showers were a great touch, the beer and the guy singing in the tent all added to a great atmosphere and we’ll definitely be back and be telling all our friends. What you guys do on the day and how it all comes together makes our experience a memorable one and for all the right reasons.


I only started training a few weeks ago when I signed up, and am not particularly fit, but had a great time all the way round, even in the muddy warm up.  It was so well-managed and manned the whole way through, from warm-up to de-brief to instructors pushing people round the course and helping at the obstacles.  All the people out in the field were friendly and encouraging, even when shouting and barking orders. A lot of the obstacles were seriously fun.”


Our whole family raced this weekend, with starter sprints, 8 year and 11 year olds and an Olympic. We all had an awesome weekend with three other families and plenty of friends doing the same. 16 races between us!


Would just like to say thanks for organising a great course. Team Dad’s Army loved it as for most of  us it was are first ever obstacle course since we were kids. Well done to your marines, still buzzing Sunday morning.
