Walking
I went for the same walk I did the other day but turned 'MapMyWalk' on this time.
According to that, it was 3.36 miles. About 300 yards of that on footpaths, the rest on rough ground. I walked up 181 feet of elevation and did 6763 paces. The round trip took 57 minutes.
Maybe not a bad time in view of having to pick the way around puddles, mud and undergrowth.
