From a dead stop, takeoff. Literally. Fly straight ahead at full-power, accelerating. You cannot land until on or past the 1-mile white line ahead. Come to a full stop, spin 180 degrees around, then ram that power in and takeoff back to the start line, where you can’t land until on or past it. At a full stop, it’s all about total elapsed time.
Did you beat the Draco? (A turbine powered 680hp Wilga) What about that light weight 140hp turbo Rotax Kitfox? Yup. A bunch of back country enthusiasts found a way to really measure an envelope of performance. This is that 0-100-0 race in a car, twice in a row. Time penalties come from landing short of the line in 10 ft. increments and not coming to a full stop on either end. It all adds up in total time. So much technique goes into making a time that can overcome most any airplane deficiency.
Here is a video form the competitor’s viewpoint. Trent makes a lot of back country videos of himself and his Kitfox.

I can think of plenty of ways to play in your spare time, but this is a new one, and I think this is an excellent way to rid yourself of those pesky and heavy bags of gold bricks you’ve been complaining about!
