London Triathlon Leagues

South London Harriers enters the leagues run by Triathlon London each year as a means of entering a structured competition in races that are local and affordable.  Two leagues are in operation; a senior series with individual and team competitions and a junior series for under 18s with an individual competition only.

Full details of the Leagues can be found at

VonCrank London Senior League

Events are selected from the region to comprise the London League, allowing clubs across London to support each others events, compete against each other and generate a healthy environment for improving performance, encouraging participation and having fun.

Details of the 2017 rules and results so far can be found on the league's homepage at

A full fixture list can also be found, along with details of SLH entrants and athletes' performances, on the 2017 triathlon fixtures page.

SLH has enjoyed success in recent years, with 2014 being a particular highlight as we finished third overall - not bad for a small club! - and with three age group winners, Caroline Cattini, Rob Drake and Tracy Land.  In the last couple of years we haven't entered teams in such large numbers, although Carolyn McNamara finished third in her age group in 2016.

We want to get back in the game in 2017 by entering scoring teams!  A scoring team in the men's league and the women's league consists of three athletes.  For the mixed league it consists of three athletes of each in the same race.  We need to achieve that in at least four of the 13 scoring rounds of the championship, at least one of which has to be a triathlon . Details will be distributes via the forum and Facebook Forum so please get involved and score for the club.  It doesn't matter if you're quick or if you've never done a triathlon before - the races are always fun and we'd like to see you!

London Junior Series

Triathlon England, through its London region, offer a structured series of multisport events for junior athletes through the season at venues across London and surrounding areas in the form of the London Junior Series.

Full details of the series can be found at and details of SLH athletes' performanes are on the 2017 fixtures page.

These events are contested on an individual - not team - basis and South London Harriers does not co-ordinate entries.  Details of the series are maintained by This e-mail address is being protected from spambots. You need JavaScript enabled to view it. , the London Junior Series Co-ordinator at Triathlon England, on the page above. 

This series is open to all juniors who are a member of a London club (such as SLH) or reside in a London Borough.

2017 Series

The Series ranking is based on the 2 best triathlon scores (1,000 point races), best aquathlon score & best duathlon score (500 point races). The maximum score therefore is 3,000 points (through winning 2 triathlons, 1 duathlon and 1 aquathlon)  - see below for Series rules and how points are calculated.

Trophies for the 1st, 2nd and 3rd placed finishers in the Series will be awarded at the End-of-Season Awards. (Note to qualify for an award an athlete must have completed the minimum number of qualifying events - 2 triathlons, 1 aquathlon & 1 duathlon).

Triathlon England offer a para-triathlon category to this years' series. There is only one event in this category but the event is open to all competitors, but only para-tri athletes will score in this event. The event is primarily about participation, however, the series para-tri winners will be chosen based on their position in this one event. For specific queries about this event contact the Artic One team directly.

See the PAST RESULTS page to access the complete set of scores and reports for the London Junior Series over recent years.

In addition events can be can be found on the British Triathlon Events Calendar.

2017 Categories

There are six age classifications based on year of birth, with a separate boys and girls category for each. The categorisation is straight-forward enough once explained, but is different to some other sports your children may already play such as football or hockey. Eligibility for an age-group is based on year of birth, and not the August/September cut-off date which others sports and indeed schools uses for a given year group. Similarly, most categories cover a period of more than 1 year. See below for the specific age categorises. For example, if you are 8 and you become 9 at any point in 2017, you would race in the Tristar1 category all year from January 2017 through to December 2017. You do not change categories on your birthday, rather like school everyone "moves up" an age category, where relevant, on the 1st January. In the example given, in 2018 this individual you would continue to race in the Tristar1 category and would "move up" to Tristar2 in January 2019. This same rational is applied across all age groups. 

These follow the definitions published by British Triathlon - see here.

  • Tristarts - 8 years old (born in 2009)
  • Tristar1 – 9/10 years old (born in 2007 / 2008)
  • Tristar2 – 11/12 years old (born in 2005 / 2006)
  • Tristar3 – 13/14 years old (born in 2003 / 2004)
  • Youth – 15/16 years old (born in 2001 / 2002)  (British Triathlon Category A)
  • Junior - 17-19 years old (born in 19978- 2000)  (British Triathlon Category B & C combined)

Junior Series Rules

Series Eligibility 

If you are a member of South London Harriers (even if you don't train with the triathletes) then there is no requirement to register to be included in the Series - the results will be compiled based on the results of the races.

Points Scoring

London Region Series Races are grouped into triathlons, duathlons and aquathlons. Scores are calculated in usual way (i.e. relative to the first London finisher), but Triathlons given greater weighting:

  • Triathlons: based on a maximum of 1,000 points
  • Duathlons / Aquathlons: based on maximum of 500points

The score for each individual in the series are is based on the cumulative points from:

-  the best 2 triathlon scores

+ the best 1 duathlon score

+ the best 1 aquathlon score

So the maximum series points available for an individual is 3,000 (1,000 + 1,000 + 500 + 500).

All athletes are awarded points based on a percentage of the 1st London athlete time for their category, and the number of points available for the type of event. Triathlons are based on 1,000 points for the leading London athlete, and aquahlons/duathlons on 500points.

e.g. First London athlete in a triathlon finishes is 20 minutes and gets 1000 points. Second London athlete is 22 minutes gets 909 points. (20/22 x 1000 = 909) and so on. This is different to previous years as we are only counting London athlete results.

IRC Selection

A London Inter-Regional Championships team (T2 & T3 categories) will be selected during the summer.
