Couch to 5k?

[Prudence]

I'm not available at a time when it's reasonable to use the IAC and it costs money I don't have. Home treadmill is paid off, available 24/7 without waiting, and comes without public mocking. The treadmill has a program which gradually cycles from slow walk to jog in 10 second intervals that I've been alternating with steady mid-speed walk for a much longer duration. I guess that's my version of the couch to 5K, except it will take me 10 years to get to the 5K point. I added a minute to the cycling one yesterday (still too short to specify) and it burned like hell for the last minute, but it doesn't hurt to walk today, which it usually does if I've overdone it.
