In reply to alasdair19:
A not too bad parkrun on Saturday, then a knackering 22.5 miles in the Pentland Hills near Edinburgh yesterday. Trails as opposed to tops in the hills, but still 2000ft ( ok, not much by fell runners standards, but still knackered me ! ).
I'm doing a flat marathon in 4 weeks ( Frankfurt ), so not sure why I was doing a hilly trail run, other than just couldn't face another boring canal run, it's all good strength training
