I got up nice and early this morning (06:30 to be precise) to try and beat the heat in the gym. I was running well with no niggling aches and feeling good but the heat still caught up with me. I only managed to make just over 4 miles before I had to reduce the pace to walking, fearing that I would end up being ill from overheating. This is ridiculous. I even wore shorts today! I don't think I'll be able to up the mileage in London until the weather changes. May have to reschedule all long runs so that I can attempt them in Cardiff. Or perhaps running outdoors would be better...
