Will what I do today affect how I'll do tomorrow?

Aspiration or underestimation?

I've only run once since last Sunday and this will go down as the lowest mileage week I've had in over a year. There's no one reason for this lapse, it's mostly circumstantial. Monday was my rest day, Tuesday was taken up with family activities, Wednesday I ran, and Thursday and Friday were days in the city that started very early and ended late. Tomorrow I'm running a 5K so I need to decide whether I should do any running or maintain my hiatus/taper.

I'm tempted to run some intervals to activate my fast twitch muscles (assuming I still have any after a week of sloth) or play out my extended rest and see if that produces a better than expected time at the race. There's an argument for both, although one involves  a lot more sweat and effort. I usually rest two days before a race, although I sometimes cut that to one day for 5K's. If I stay on the rest vector and do well, it might result in a new taper strategy for future races.

Given my utter lack of focused training for this race, my goal for tomorrow is to finish below 27:50. If I met that goal it would be the slowest 5K I've ever competitively run, but I'd still be okay with it.
