Ran first 3 miles continous in 23:08, improvement of 1 minute, somewhat expected as the second time usually is a big improvement. Then rested for just 2 minutes (last time rested for 3 minutes) and did 3/2's for 3 more miles. In a total time of 51:35. Huge PR for 6 miles. But 2 of those minutes were expected. Still had an additional 25 seconds of extra improvement in the 3/2's, which did feel kind of fast. Think the sit-ups are really helping.
Next week back to just running twice. Three times a week just doesn't feel right mentally, even with having the whole week off. Did run 24 miles this week, which I guess is the most I've ever run.
I think I want to try a continous run of 6 miles, followed by 6 miles of 3/2's. Maybe try that once next week.... Eventually hoping to do two 15 mile runs each week.
