Nienke Hensbroek

Nienke Hensbroek

Swim for Tri Coach

Nienke’s triathlon journey started just in February 2015 with learning how to swim front crawl properly. Very quickly she became hooked on swimming and triathlon. She got to know Swim for Tri during our Open Water Swim Camp in Lanzarote, and she says a whole new world of drills and structured technical sessions opened before her eyes, and showed her how important the technical aspect of swimming was. More consistency in training over the last year has brought her swim times come down significantly,. It also meant that she was able to qualify as an age grouper for GBR at the European Middle Distance Championships (ETU) in 2018 and the European Olympic Distance Championships (ETU) in 2019.

As a coach, she understand the process and effort adult triathletes without swimming background need to work their way through from her own recent experience, whether it is in the pool or open water. She enjoys sharing this knowledge, and helping any swimmer to work become better and get completely hooked on swimming.

Nienke focuses on front crawl.

Astrid Wharton

Astrid Wharton

Swim for Tri coach

Astrid is a Level 2 Coach; Open Water instructor and Swim Teacher and has been coaching since 2013.

Astrid has taught swimmers from 3yrs to 65+yrs. She is a sprint specialist and started her coaching career as the Head Coach to Queen Mary & Barts University. Following her initial role Astrid’s coaching career has taken her to being an Assistant Head Coach and Lead for Development and Performance squads from County through to National level for a number of Swim Clubs based in London as well as the Head Coach for the Bank of America Merrill Lynch Triathlon Team. She is currently the Senior Coach Lead for the County & Regional performance squads as well as the lead coach for the Open Water programme at Hackney Aquatics Club.

During a 2 wk family holiday when Astrid refused to go anywhere near the water, she eventually ventured into the sea on the last day, aged 3, and has been swimming ever since.

Despite having to cut her time as club swimmer early on where she specialised in 50 FC and 50 BK, Astrid continued to indulge in her love of sports; gymnastics; slalom canoeing; rock climbing to name but a few and returned back to swimming as a Masters swimmer and has enjoyed considerable success including competing at the LEN Masters European & World FINA Masters Championships.

Coaching philosophy:

An absolute stickler for the technical side of swimming, Astrid shares her passion of the water and makes swimming fun to learn - believing in small goals and hard work pave the way to better successes in the future.

‘Mental training I believe plays a huge part of athletes achieving success in such a technical sport. I ask athletes to set their own goals ….to trust the process and keep working on the small things and to self-reflect and acknowledge their achievements. I coach by giving the athletes guidance and awareness in making technical adjustments that will best adapt the stroke to their physique - anyone can get fit - not everyone can achieve technical greatness’.
