Went for a morning run around the Gorhambury estate, from St Alban's, with map, after a night out in the city. The estate is really beautiful - a long road going deep in, away from the noise of the city, and climbing gradually up to Gorhambury House, which has a distinctive "White House" style portico and a grand, peaceful location amongst parkland and rolling hills and forests - all only few miles away from 3 motorways! Generally, I ran for 5-15 minutes, then would walk for up to 1 minute, to prevent over-doing it.
Unfortunately, I felt a twinge in my back after 8km, so I stopped the run, and restarted it again 25 minutes and 2km later (not counted in the distance above.) As luck would have it, this point was furthest away from the start... I'm surprised I was able to start running again - the back pain is something I last suffered back in October 2004, it is normally very painful (especially when lounging, as I am now) but normally clears itself up in a couple of days. I'll be doing non-impact training only next week (i.e. cycling) to aid swift recovery before the big race next Sunday.
I felt really awful afterwards - I think I seriously over-exerted myself on this training, and didn't warm down properly - and feel really bad now. It's a little distressing that I can't do any serious exercise without feeling bad. It's going to be a long hill to climb before I regain the fitness I used to have back a few years ago.
My route - ran anticlockwise. I walked most of the section south of the motorway. Also, automatically generated
altitude profile - how cool is that?
