Yeah, just don't do two long days back to back, is all I'm saying. If you are running 6 days a week, 2 or 3 of those days should be longer days.
So maybe do: 2 on monday, 3 on tuesday, 2 on wednesday, 4 on thursday, 2 on friday, 3 on saturday
Then the next week:
2 on monday, 4 on tuesday, 2 on wednesday, 4 on thursday, 2 on friday, 3 on saturday
Then:
2 on monday, 5 on tuesday, 2 on wednesday, 4 on thursday, 2 on friday, 4 on saturday
Etc:
You only want to increase your total weekly mileage by about 10% each week.
