I'm running a trail 5K this weekend. I'm happy to be healthy enough to comfortably run anything right now, and this one has been on my to-do list for awhile. Not looking to race or place or anything- if I do it in less than 40 minutes, I'll be happy.

With that said, when should my last run be before Saturday? My free time is limited this week, but Friday is wide open. If I run Friday morning, am I going to kill my legs for Saturday?

Thanks in advance for any advice that y'all may have.
