Triathlon & Open Water Training Race Series 

OWSC, Berinsfield, Oxfordshire

Come along and practice your race skills in these friendly races. Get some top tips in a short coached warm up before lining up to practice your mass starts, sighting and navigation, technique and drafting skills. Suitable for any ability of open water swimmer and triathlete looking to have a practice swim to see what time you can expect in your A race this season. Or just come for fun and a small amount of healthy local competition! 

Our sessions will help you feel more confident getting your face in the water, dealing with this new environment and help you learn some new skills, perfect if you're completing your first few triathlons or just getting into open water swimming.

Perhaps you've got a big race coming up and want to get used to the washing machine effect and inevitable physical contact of the mass start, or just need a quick refresher course.


These training races are designed to tune up your existing skills and give you a chance to learn and practice some new ones to help you race at your best. 

Put your pacing to the test and see whether you predicted finish time is accurate so you know what you're capeable of.
