Lately I've been doing the following, and it seems to be helping a lot. I'm training for an early September half marathon and then starting to train for January in WDW...doing W&D as well.

- 4 days per week of running - 3 at easy pace and one that is either speedwork intervals or a tempo run - 2 days per week of strength training With the speedwork I have been doing 0.25-mile intervals at 5K pace (started with 5, going to work up to 10 eventually)...with the tempo runs I start out slowly, and then gradually built up until I'm at peak speed (10K pace) about two-thirds into the run. Then do a cooldown. So for me, I think it's been a combination of gaining endurance (the 3 easy runs per week, especially my long runs), 1 day of faster running (speedwork or tempo run...alternate one or the other each week) and strength training. I'm sure you'll get back to 10:00/mile pace!!
