Serpentine is not just for runners.  We also have a keen group of triathletes from novices to age groupers and Ironman competitors.  We are affiliated with British Triathlon and are members of the London Triathlon League.  Serpentine is a Triathlon England registered Club and this gives you a discount on your individual British Triathlon membership.  Being a British Triathlon member saves loads on race entries over the course of a year.

Triathlon Training

Serpentine offers a range of coached run and swim sessions detailed in the Training Diary.  Please see this list of coaches for our coached sessions, and a swim training plan written for us by the coaches at Swim for Tri.

Once the water has warmed up in the spring there are coached open water sessions at Shepperton Lake.

Informal group rides are organised by group members via the Triathlon Chat WhatsApp group.   In addition, there is a weekly spin class held at the Seymour Leisure Centre on Wednesday evening.

Serpentine members participate in a huge range of races during the year.  To plan your future races look at the Serpentine Race Planner, which tries to list all the triathlon, duathlon and cycling events that could be of interest to Serpies in the coming months. Use MyEvents to see who else is racing and tell others you are going.  There is also an active WhatsApp group where members can discuss their race plans.

Races that the club focuses on include:

  • Club Championships – compete to be the best Serpentine member over the various distances and disciplines.
  •  London League – score points for Serpentine by taking part in various London area triathlons, duathlons and aquathlons.
  •  National Club Relays – compete as a team in a relay event where everyone swims, bikes and runs.
