TESE Senior Series 2023

We are pleased to announce details for the Triathlon England South East (TESE) Region Club Senior Series for 2023. The series will follow the same format as the 2022 Senior Series. The series retains its age adjustement formula for the overall classification, allowing athletes of all ages to compete on a level playing field. Brighton Triathlon Club are defending champions having taken the title from Epsom Triathlon Club last year. 

This years series kicks off with two club events in Sevenoaks and East Grinstead, before heading to the BTF Major Event at Eastbourne, where athletes can score points in the series whilst simultaniously attempting to qualify for the GB Age-Group Team at standard distance.

At Dartford Triathlon participants will benefit from a completely closed roads race, as will they at Goodwood Duathlon on a closed roads motor racing circuit. Southwater Relays provides the season finale this year and you must enter as a mixed gendered team to score. 

The events are:

How does it work?

  1. Athletes score points for their clubs at 6 races across the south east over the season.

  2. In a given classification, each clubs best 3 events (out of 6) will count towards their final total. 

  3. At the end of the season, prizes are awarded across 5 different classifications.

  4. The winner of the 2023 senior series, is the winner of the ‘Overall Classification’ which combines both genders with results weighed and then adjusted according to age-group. 

What’s on offer?

Athletes who represent their clubs in the TESE Senior Series will score points in the following competitions:

Overall Club Championship – For the club with the fastest mixed gender team after results have been adjusted for age. Winners of the Overall Club Championship gain the title club champions of the south east. 

Open Classification – For the club with the outright fastest open team (formerly known as the Men's Classification).

Womens Classification – For the club with the outright fastest women’s team.

Best mixed team– For the fastest club when points in the open and female classifications are combined.

Mob Classification - The club with the highest participation across all 6 races, regardless of athletes placings. 


How does my club enter the Senior Series?

All TESE affiliated clubs can enter the Senior Series by sending an email to containing your club name, club contact details, your name and your position within your club.  

There is no registration fee. Please nominate a club co-ordinator when registering your club and please encourage your triathletes to wear club team kit when racing in the Senior Series, to promote and advertise TESE clubs.

All clubs that were in the 2022 Senior Series are automatically entered for 2023. Clubs are also free to leave by sending an email to A full list of currently entered clubs is available here.


Can my club enter the Senior Series even if the first race has already taken place?

Yes, but your club will only be able to score points at races that have not yet occured at the time of joining, not retrospectively. 


How do individual club members enter the races in the Senior Series?

Members from each club must enter the races as individuals under their club name and pay their own entry fee. Please enter events early to avoid disappointment when they sell-out. Please take care to enter the correct event, as some have more than one distance on offer.

If the club name is not included so it appears on the results, no time will be recorded towards the Senior Series. Please ensure your entry includes your club details before the event. We cannot guarentee an opportunity to retrospectively add your club name after the event and there is no right of appeal if your club name is not shown on the results.

Please take particular care when entering a team name at the Southwater Relays. Your team name should make it obvious what club you represent. Examples of good team names are "Brighton Triathlon Team A" or "The Jammy Dodgers (Brighton Tri)"

Triathletes must be paid up club members and can only race for one TESE club in any calendar year.


What is the scoring system for the Female, Open and Mixed team series?

Female and open results sheets are scored separately. For the female and open competitions, the last placed athlete picks up 1 athlete point, the second last 2 athlete points, and so on all the way up to the winner.

The total athlete points scored by the three highest placed open finishers from each club gives the points total in the Open Classification. The total athlete points scored by the three highest placed female finishers from each club gives the points total in the Female classification. The winning club in any given classification is the one with the most athlete points. Clubs with less than three athletes may still score points albeit less than might have been scored with a full team.  

Once athlete points have been totalled to decide the placings at an event, points in the series are then awarded based on each clubs finishing position. The first place team scores 50 TESE points, second place 40 TESE points, and so on as follows:

1st:   50                 11th : 10

2nd :  40               12th : 9

3rd :  32                13th : 8

4th :  26                14th : 7

5th :   22               15th : 6

6th: 20                  16th: 5

7th: 18                   17th: 4

8th: 16                   18th: 3

9th: 14                   19th: 2

10th: 12                 20th: 1

Any clubs below 20th will also score 1 point. 

The Mixed classification is calculated by simply adding TESE points scored in the Open Classification to TESE points scored in the Female Classification. 

In the event of a tie on points at the end of the Senior Series for any team competition, the winner will be the team which scores the most points at the relay event. If there is still a tie the title will be shared. 

NOTE: The scoring for the Southwater relays will be based on each clubs single fastest mixed relay team. Single gendered teams teams will not score, so make sure you are in mixed team to score points in the series.


What is the scoring system for the Overall Club Championships?

Athletes are classified as belonging to one of 4 age groups, U40 (Senior), 40-49 (Veteran), 50-59 (Super Veteran), 60+ (Vintage).

Athlete’s times are adjusted according to an age-weighting. Athlete’s times (in seconds) are multiplied by the age-weighting of their age-group for the open and female results separately. Result sheets are then reordered to produce age-adjusted results, with more senior athletes advancing up the table to varying degrees based on age-group.

The age-weightings for the 2023 series are unchanged and as follows:


















As before, the last placed athlete is assigned one athlete point, the second last two athlete points and so on up to the age-adjusted winner. 50 TESE points will be assigned to the winning open team and 50 TESE points to the winning female team and so on as previously described. Finally, open and female points are added together. Thus the maximum score from any event in the overall championship is 100.

NOTE: The age-weighting applied to vets teams at the Southwater Relays will be half way between the 40-49 age-weighting and the 50-59 age-weighting, averaged across both genders. That comes to 0.949049.


How did you calculate the age-weightings?

We analysed results from four years of age-group sprint distance triathlon World and European championships between 2015 and 2018. Age-weightings were calculated by dividing the mean time of the top 5 athletes in the U40 category by the mean time of the top 5 athletes in each age-group, averaged across 16 internationals (8 male, 8 female). The age-weighting is a best estimate of how ageing impacts performance in age-group triathlon, and provides the basis for times to be adjusted accordingly.

If you love the numbers, a full excel spreadsheet is available here: weighting-function.xlsx


Do I have to be over 18 to participate in the series?

There is no age-limit on participation in the senior series as such. If you are old enough to enter the races, then you are old enough to participate in the series. How old you need to be to participate in any given senior series event is a decision taken by individual race organisers. If you're on the results sheet, you're in the series. 


Results and Senior Series standings

Senior Series rankings will be published on the Triathlon England South East Senior Series facebook page after each race. You can find last years results here.

In the event of any disputes, the TESE committee’s decision will be final.
