It is really hot these days and the sun is shining bright at 6:45am. I prefer morning runs as such but the heat is just killing me and my stamina. The worst part is it is sunny till around 6:30pm in the evening too. I eat dinner at around 7pm as such. I have major heat issues like headaches, nausea and frankly at times I feel I will faint(which has happened twice before). The gym is really far and is not a choice. Any suggestions please? I haven't made it for a single run in the past 3 days now.
