Mile two we turned off the gravelly backroad we were on onto a tarmac road and into a head wind. I had forgotten this bit was quite hilly and got a bit worried that I was expending too much energy and wouldn't have anything for the last mile which was all uphill. Oh dear! Anyway I obviously let this get in my head as the next mile was 7:04. So I was obviously slowing but it didn't feel that way as I kept passing people.
