Updated 28 July

Most of our sessions are now running again, but with reduced capacity. All details on the members' WhatsApp group.




All of the coaches involved with the Junior section hold British Triathlon coaching qualifications and current DBS credentials.

If you would like to find out what one of our training is like please come along to one of our sessions and join in! Check here regularly to keep up to date with our training schedules.

Our swim bike and run sessions are designed to get athletes ready for the demands of age group racing. Typical race distances are:

9/10 years: 150m/4km/1.2km 

11/12 years: 200m/6km/1.8km

13/14 years: 300m/8km/2.4km

15/16 years: 400m/10km/2.5km

Please note that we do not operate a "learn to swim" programme. Our sessions are triathlon specific and primarily about building endurance for swimmers that have already mastered the fundamentals of freestyle swimming (ASA Level 7). If your child is interested in coming to our swim sessions please contact us so that we can arrange a trial (100m continuous swimming for 9-12 year olds, 200m for older children) to ensure that they are at the appropriate standard. If your child does not meet our minimum standard we recommend that they join a club that offers a structured ASA learn to swim programme before coming to Tritons' swim sessions. 

We get lots of questions about the cycling sessions - how good a cyclist do I have to be? do I need a fancy racing bike? etc. We are able to cater for a wide range of cycling abilities at Herne Hill but to benefit from these sessions you should be able to ride safely and have mastered basic handling skills - ride in a straight line, follow a line round a bend, and turn a corner, brake and stop under control. Any bike is fine as long as it is roadworthy and the right size for you. 

Our winter 2019/20 training programme is as follows (change to summer timetable from the beginning of April):

Tuesday evening - swimming at Charlton Lido 6-7pm 

Wednesday evening - running at Sutcliffe Park track 5-6pm (summer: Greenwich Park 6-7pm)

Thursday evening - turbo session at Old Colfeians 7-8pm (summer: Greenwich Park 6-7pm)  

Sunday morning - cycling at Herne Hill Velodrome 9-11am 

Sunday evening - swimming at Eltham College. Sessions run 6-7pm for Group 1, 7-8pm for Group 2 and 6:30-8pm for Group 3. Check with the coach if you are unsure which group you are in. You will need a kick board, pull buoy and fins. 

All regular training sessions are free for Full members or £7.50 for Associate members.
