So today I ran the British 10k in London in the sweltering heat! Those of you in the UK will be aware that we have been going through a heatwave for the past few weeks, with temperatures reaching just over 31 degrees celsius. Arriving at Piccadilly Circus, I was guided by stewards to the baggage bays, a 5 minute walk away. Not bad, I thought. However, there is an additional 1.5 km walk just to get to the start. Not ideal, and given that there were a limited number of toilets before the race (with long queues), I was not particularly happy.
