Looking to step it up from your 5k?  Already a 10K runner but want to kick it up a notch?  Or are you a seasoned athlete in conditioned shape that wants to challenge yourself to a 10K?  Then this plan is for you.  For those new to 10K's you can opt to exclude the speed work, but not the mileage on the speed days.  For seasoned 10k'ers, the speed work in this plan will help you reach your time goals.  This plan is a 4 day a week plan with additional cross training days.  Your weekly mileage starts off at 8m/wk and peaks at 19.5m/wk right before your 2 week taper.  At 11 weeks long and 4 days of running, this is a flexible plan that feels just right.
