Janine, I would suggest you Janine, I would suggest you do a SINGLE 10 next week and then cut back to 8 for the following two weeks. No more back to back long runs... A trend I notice around the barefoot world that is NOT conducive to good race times is LOW weekly volume with like 50% or more of your mileage coming from the long run. This is NOT good training. The long run should not be more than 20% of your weekly mileage. Run more and less long. Unless you are training for a 100 mile race or something Up you weekly miles and keep the long run at or near 20%.
