As usual, there is no right or wrong answer to your question.
I haven’t been cycling for the past 2 days because it is very hot outside and I don’t want to risk fainting as I have fainted in the past.It was too hot today. 30°C is my limit. The bigger you are, the less surface area you have in relation to your volume, the harder it is to shed excess heat. I'm a big laddie, and I'm not risking illness, injury or worse going for a ride in this.
