running on a treadmill
Hi all! This may be me being stupid, but how accurate are the speeds on a treadmill? The reason I ask is that I can normally run on the road at a steady 11/12 KMPH with no problems. Today I went on a treadmill as I am at sea on a ship for the next 5 weeks and was almost sprinting at 12 KMPH and my HR was far higher than normal. In fact to run at a comfortable pace which felt like I was road running I had to drop to 9 KMPH. Any got any thoughts??
