Hello, I'm Marianne.

Over the last 5 years in Team GB, I've stood on 10 international podiums and won two World and two European Championships. I've also worked with some of the top coaches in the game.

I bring everything I've learnt along the way to my run and triathlon coaching. I am passionate about delivering performance for any ability - whether you're training to complete a 10k run, or aiming for the top spot at your next Championships.

From gear ratios and waxed chains, to lactate testing and carbon shoes, and from rolling resistance and aerodynamics, to open water swim sighting and race nutrition, I leave no stone unturned in coaching you to be the very fastest version of yourself.
