Well, I went out late-ish last night (about 9.15pm) to do my regular intervals session, and decided to go with the Speed podcast rather than using Week 1, basically because it's a little shorter!
I use this one regularly; sometimes it goes well, sometimes I walk bits of the slow sections. Last night was great! I don't know if it was the confidence continuing from Saturday's 5k, the nice evening, whatever, but although bits of it were tough, I was tougher! At one point there were a couple of 'young ladies' smoking and giggling in a bus stop, but I decided that I really truly didn't care whether they were giggling at me. If they were, it was their problem; if they weren't, then it didn't bother me either!
Got home feeling tired but oh so victorious - and discovered that this had been my quickest Speed session yet. Presumably that means I'm learning to lengthen my stride slightly rather than just having to take little steps to get them in quick enough. So yes, happy happy
