The speedrun challenge has no downside!

If you just beat it in less than 37 minutes its a normal run!

(Of course, getting through it this fast was not easy. I'd be interested what other peoples' record times are. This was my last of the "first set" of challenges. There's only the final challenge left, I assume clearing that will help with speedrun at least a little.)

I take it that the timer is in-game, so time pieces to warp is counted for? Or could you cheese the timer if it counts real world time and make use of those?

Edit: Never mind, re-read the description for speedrun, says in-game timer, so no.
Edit 2: I did it in 1 hour 1 min.
