It's mostly run on grassy footpaths with just a bit of road in it.
It's 2.68 miles long (thanks Garmin) and I did it today in 26.07. This isn't very quick in absolute terms (my average moving pace was 09:23 min/mile), but on looking back at my Garmin records, my best time from a couple of years ago was 26.04 - so maybe I was close to my PB today! I actually felt quite good too. I pushed up all the hills, tried to push over the tops and then did a couple of fartlek-y bits on the way back.
Not much to report other than I did it. Definitely more sheep about. It won't be long before we have the fun of lambs to look at (that'll slow things down a bit!) so it's a great time of year.
