London Junior Series Events

Qualification to the London Series

To be entered for the London Junior Race Series athletes must either live within the London area or be a current member of a London Triathlon registered club and be a British Triathlon Home Nation member. The regional affiliation MUST be set to London and reflected in your Junior membership or your results will not be included. This is NOT automatic based on club membership or which region you competed previously.

Further Information

If you want your performance in the series events to count to the London Junior Series then you need to make sure that you are a British Triathlon member and that your Region assigned to your membership is “London”. If you’ve joined British Triathlon since you entered the event please send the event organiser your BTF membership number before the event and they should be able to update your details.

To check your region, log on to your British Triathlon account. Then in the “my profile” click the “manage profile” button and in the address drop down you can see the “region” assigned to your membership. You can change your region to “London” here.


If you need help with your login, lost password etc, contact and they will be able to help or give them a call on 01509 226 153

NB. The default region is associated with your Triathlon membership and is based on your postcode, which is not always the region you would expect. Please also note, results cannot be added retrospectively to the series standings once you have amended this field. Only those results obtained after this is set to London can be added to the series standings.

The regional series is open to athletes between the ages of 8 & 19 (age as of December 31st 2020)


There are six age classifications based on year of birth. Age for each group are as of 31st December 2020:

  • TriStar Start: 8 years old (born 2012)
  • TriStar 1: 9-10 years old (born 2010 / 2011)
  • TriStar 2: 11-12 years old (born 2008 / 2009)
  • TriStar 3: 13-14 years old (born 2006 / 2007)

  • Junior: 17-19 years old (born 2002 / 2003)

Final 2019 Standings

The Current Standing page is not able to calculate our season ending points completely accurately as it takes the best 4 results and this does not always include a triathlon. We have defined that the overall score must include at least 1 triathlon. As such the final standings have to be re-organised manually. The final standing can be found here

Series Events 2020

Most of the events for 2020 have been confirmed so please see below for updated information. The only possible addition is an open water aquathlon (which might form part of IRC qualification for TS2 athletes) and another open water triathlon at a major event. This will all be confirmed by the end of January.  

Until all events are confirmed, the scoring system for the 2020 Series similarly can't be confirmed.  IRC and IRD qualification will be made clear at the same time as the scoring system.

Current Standings

How are points calculated?

The London Junior Race Series is governed by the London Triathlon Regional Committee. All races are sanctioned by British Triathlon and therefore competitors and spectators must abide by the rules of the British Triathlon.  

Points are calculated based on the first London finisher's time with this athlete receiving 1000 points (occasionally a non-London athletes may win a London series events, but for the league purposes we ignore any such athlete and award the first London finisher 1000 points and calculate all points based on the time achieved by the first London finisher). Subsequent results are calculated by dividing the winning time by the recorded time for all other athletes and multiplying the result by 1000 (eg winner in 18mins gets 1000pts,  2nd place finishes in 18 minutes 36 seconds. 18 mins divided by 18mins 36 seconds * 1000 = 968 and therefore the 2nd place finisher would would receive 968 points for that race).

If a race is cancelled or is deemed not to have met the level of quality that we require from a race then the committee have the right to amend the number of points scored by all athletes and may amend the number of qualifying races to count in the series.
