I thought I’d manage 2k / 2k-4/3/2/1. But I ended up nowhere near that towards the end:
So I’ll have another go tomorrow (which truth be told I’m not looking forward to!) and try to hold the 333 at 1:39 instead of going hard. Then hopefully the next three intervals will be comparatively faster and still give me a better time.
The big question though is whether I can do the 1111 faster?
