My training plan has a few recovery weeks built in, so i think I may count this weekend's runs as that. For Week 4, I'll try the Week 3 plan again with a few modifications.
Monday - Off
Tuesday - 6 miles (speed work)
Wednesday - 5 miles (holiday fun run)
Thursday - X-training
Friday - Off
Saturday - 15 miles
Sunday -X-training
Judging by my run today, I should be back to normal health-wise by Monday. I'm crossing my fingers. Plus, the bright side of being sick was that I was able to give my IT band several rest days, and it didn't bother me at all on my runs this week.
