Did a session this morning. Did 2x100m, 2x200m, 2x100m w 15s rest then cracked on with a 400m. Got it in 7.17, so I smashed my pb which I'm really happy with, although to be fair I'd never actually gone all out for a 400m before, they were always part of other sets. I wasn't sure what time I was aiming for, so pacing was tricky. I know what I time I can do now so I think I can shave maybe another 5-10s off pretty quickly with better pacing.
Finished off with 1x100m, 1x200m, 1x100m w 15s rest to total 1600m (plus warm-ups/cool-downs) which is the most I've ever managed in a session.
Just have to say I thought that being effortlessly passed by a teenage girl (who was in the middle of a 1k+ set) when you're setting a PB would be pretty demoralising, but I actually found it quite motivational!
