NTri Juniors is the children’s section of Northants Triathlon Club. NTri Juniors was formed in 2010 by parents from the adult club who wanted to give their eager kids an opportunity to join in the fun.

The club is for kids of all abilities from the ages of 8 to 17. The only basic requirement is that you can swim 50 metres unaided and have access to a roadworthy cycle.

We set a priority on having fun and schedule in lots of different activities to keep the training varied and enjoyable. All training sessions are run in accordance with British Triathlon Federation guidance regarding the training and development of young athletes and are geared towards improving skills, techniques and fitness levels.

What is Junior Triathlon?



Junior Triathlon starts with the swim. This is normally held in an indoors pool and features a staggered start to allow  young triathletes the space to swim at their own pace.




Next up is the bike section, which is always held off road to ensure kids are safe. The course will likely be a mixture of flat grass and tarmac to provide a variety of terrain.



The race finishes with the run. Kids need to have made sure they have paced themselves correctly so they have enough energy to cross the finish line… to cheers from the waiting crowds.

What our parents say

My lad has been a water baby all his life. However, his swimming club were looking to get him train 4 to 5 times a week and eventually he just got bored. He had a taster session with NTri in Abington Park just before the Summer Holidays and had a brilliant time.  He could not wait until the new term began, so that he could get into the training.  Now twice a week he trains at all three disciplines.  I love how enthusiastic he is and the fact that he is always ready to go when the day comes.

“Our daughter was a member of a running club previously, but found training for a single sport a tad repetitive. Since joining NTri she has come on in leaps and bounds. Her swimming has improved immensely, she has gone from barely being able to swim 50 metres to clocking up 2km each session. She has made some great friends through the club and I have to say… so have we!”

“We are delighted with the progress our child has made since joining NTri. They have grown both athletically and socially. I would just like to take this opportunity to thank all the coaches and volunteers for their efforts over the years.”
