5k tonight, took me 35 mins. I am sooooo knackered today. I really felt like stopping every couple of minutes. Commuting is a weird thing; it's not like I'm actually doing anything demanding, but when I get back from the London to Brighton journey and then immediately go running, I always feel like I can barely keep my eyes open. Even while I'm running, I'm yawning.

Also, and this may be a contributing factor, I don't know - but I've run four consecutive nights in a row now: Monday half an hour all uphill, Tuesday 5km, Wednesday 3.5km (to Spock's house) which was a long slow uphill to Seven Dials, and then all downhill save for one last hill at the end. I need to work on running downhill. I find it really hard on the old knees, very jarring. So I'm pretty shattered.
