Week 4 of the program calls for runs of 3, 6 and 3 miles and then 11 on the weekend. However, I'm planning to run Riley's Rumble on Sunday - so that will be 13 miles. As a result, I'm going to do an extra mile on one of the 3 mile runs, so I'm still within the rule that the longest run is not more than 50% of my weekly mileage.
I'll likely run 4 miles on Monday morning, 6 miles on my lunch break on Wednesday and 3 miles on Friday morning. Then the 13 mile race (as a training run - I'm not going for a PR or anything) on Sunday morning. It seems nice and spaced out, so I hopefully will be able to get a good amount of sleep and recovery between the runs.
