I'm not sure about that Jackson's Lane-Sunny Hill loop. Sunny Hill is road and there isn't much of that on the BG. I'd stick to just going up and down Jackson's Lane. Boring, but the descent would be much harder than the road of Sunny Hill. Do that ten times, jog along to the end of the Chevin, head down to the river, run back to Milford, then another 5 - 10 reps on Jackson's Lane. That should sort it. Although, of course, Derby Tup is fundamentally right: the BG is not a run, it's nowt but a walk.
