Times Cryptic No 29093 — A marathon, not a sprint?

43:39. Well, that’s how I felt solving this puzzle anyway. Don’t get me wrong, there were a lot of absolutely delightful clues here (meaning surface reading, wordplay, word choice, etc), but I felt that a fair amount of the difficulty for me stemmed from using very uncommon synonyms or abbreviations. But let me parse the clues and I’ll get back to you.

Times Cryptic No 29021 — Lift and separate

DNF. I think a lot of the wordplay here was quite tricky (more lifting and separating than you might find in a pilates class), but I fairly raced through this one until I got to the upper-left corner. After 15 minutes of beard-scratching, I still wasn’t able to get 1 Across or Down, so I threw in the towel.
