Run 1:08:00 [3] 11.4 km (5:58 / km)
Had hopes for something big today (was aiming for 100-105) but it wasn't to be - had the sort of low-level back tightness in the first couple of kilometres that normally disappears eventually, but today it never did - not bad enough to stop me but bad enough to make it a struggle all the way (as indicated by the pace, which I don't think I can completely blame on 30 minutes of darkness).
