Anyone know of a treadmill (or treadmill control system?) that allows the user to program custom workouts with detailed intervals? For example, if one would want to program in half-mile intervals with 200m active recovery or, better yet, an ascending and descending ladder workout based on distance. It's always a pain to hawkeye the distance numbers while trying to hammer in the quick speed changes and remember the funky numbers that make up either the total distance or time after you're in oxygen debt.

Outdoor tracks are covered in snow and ice this time of year and indoor tracks by herds of social walkers and joggers.
