I think most people on the message board agree that some runners can taper for big races (even up to 50% in volume) and run fantastically while others who drop more than %20 feel flat and horrible on raceday. Some runners even go to the extent of keeping 90% of their mileage and just cutting back on the intensity.
Why is this? I'm sure the answer is a complicated one but what are most peoples thoughts on why runners react differently to tapering.
