Mojo back?

Went for a run tonight without doing anything else hard first, like, say, bicycling up 1200 feet of climb. Much easier.

Managed my best 4 mile time in like 2.5 years. Heart rate was lower than last week. Have been playing around with surges of speed in the run lately rather than trying to grind out a steady pace regardless of incline/decline. It's more fun, and hopefully will condition me to processing lactic acid better.
