Pot hole in the road during a 10k London race at the weekend, organisers and street workers on the scene could see a potential hazard but did not put adequate safety warnings or move cones to cover the pot hole. I enclose photos and have a video showing the hazard to runners. I am complaining as I fell at this point, I am over 20yrs experience in running races and I fell and badly sprained and damaged my ankle, I consequently could not finish the race.. I could not get to the hospital as roads were closed and paid for an Uber to A +E I am not able to work as I’m a nurse in the NHS and the job requires me to be able to walk independently, also I have 2 children who I look after and have needed extra support at a cost to myself. Please can you address this and I wish to make a formal complaint and claim. I have also contacted the race organisers.
