40d could be scoot ?

[peter210360]

All done, but I'm having difficulty with 44a and 40d.
44a I think is probably prone, but it's not a great single word clue.
40d I thought might be spurt, shoot (as in a plant stem for 'rush'), but scoot doesn't sound right.
It can't be 'sprint' dgtblue - too many letters.
Thoughts anyone?
