Brassica - I've just looked it up and your W2R2 is the same as W1R2, so I don't know why your internal voices are managing to give you a negative message considering you've ALREADY run this. If you've done it once, you can do it again! And, in my opinion, it must be easier than the W2R1 run you've also, already, done, so you can certainly crack this! (I think I'm planning on staying on W1 forever - the rest of it scares me!)
I've got the Shred. Somewhere. I suspect it's in the far section of the TV unit, which will require some serious furniture moving to get to. I tried it once, and failed, miserable. Though, given all the running I've been doing I suppose I'm fitter and thus should find it easier...? I might get it out at some point and try.
I'm lucky that there's a small gym at my work. I can understand you not wanting to add an hour's travel to your workout. You really are braver than me, I hate the thought at anyone seeing my pathetic attempts at 'running'! I'll try not to wish banana slaloms on you if you have mud to deal with ('trying' being the operative word, you understand!).
As for music, I downloaded The Very Best Running Tracks album from Amazon. I don't tend to have a great selection of music, and I figured that given its title, and the fact there are 105 tracks on it, it should keep me going for a while. Reading the reviews it's not the best if you're into your music (they're all covers, which I hadn't noticed!) but it suits me, and it was cheap. Some of the songs are a bit dire, but then something will start which I like and that will keep me going.
Which podcasts are you listening to? I was thinking about Woman's Hour, but, like you, suspect I really need a beat to keep me moving, rather than just talk.
