The Challenge takes place every year near the end of September with the goal of raising as much as possible for Guy’s and St. Thomas’ and the Evelina Children’s Hospital. I was there as nearly 300 participants took on London’s most popular urban triathlon, making the day a great success.

This high adrenaline event asks a lot of its participants, with a 2.4km run, a 15km spin cycle and ending with a 29 floor stair climb to the top of Guy’s Tower (Europe’s tallest hospital building)! There’s even an ultra version for those who want to double their run time and cycle for longer. It’s a huge achievement for anyone who takes part. Perhaps the best part of this well run event is the very real sense of community and support that exists among those taking part. I certainly felt it as I snapped throughout the day. These are families who are doing something very personal and important to them and I salute them for it.
