So, today was the two 8 minute runs, and it was fine. I took the first one slowly, and as that went okay, I decided to go a bit faster for the second one. I definitely felt the breathing was harder, but my body manages okay. I feel that I'm carrying too much weight while I run with heavy legs etc., but I must have a certain amount of muscular fitness that carries me through. It's the breathing and overheating that does me in. I have the same thing when I do long treks on holiday, I get out of breath rather than feeling physically tired. If anything I feel energised by the physical aspect. As an occasional user of an asthma inhaler, I'm thinking I might be able to help myself by working on lung capacity. Is this the same for anyone else? I'm wondering about using the inhaler before/during runs (although I wouldn't normally use it more than once or twice a month), and pushing with a faster running rate to make sure my lungs are being used to the maximum?
Update about arch blisters - I applied talc and laced my shoes tighter and it was fine again, but still intending to get running socks.
