Muggy summertime has finally hit New England. I did 4.5 slow recovery miles after Thursday's mile intervals. I just bought Jack Daniel's Running Formula Book. On first glance it seems like I may be running long runs a bit fast. I also wonder if Daniels considers mile intervals at 10K pace to be speedwork that shouldn't exceed eight percent of weekly mileage. I suppose that's another arguement for raising weekly mileage totals to 60. |
