I did this mile a week or so ago. just got around to posting.
I did the regular loop which, at the moment, is just too overgrown to give myself a chance of beating my mile time.

But gave it a go anyway: 6.53
Found the last part up the hill particularly difficult. Legs had nothing in them. Together with the very overgrown path it was a struggle to beat previous best. So overall time was 9 secs slower than best yet.
- Attempt 1 – 6.55
- Attempt 2 – 6.48
- Attempt 3 – 6.45
- Attempt 4 – 6.44
- Attempt 5 – 6.53
The next go may have to be on a new mile course.
