Evening retards Having grown sick and tired of the number of bone, inane and otherwise irrelevant queries about running on a conveyer belt, I have spent an evening at the gym figuring out why some newbies are struggling to run on these things compared with the road etc. Initially putting it down to lazy dullards allergic to sweating in a gym, I have changed my mind, and will endeavour to help. Not because I like any of you, you understand, it's just if I read another treadmill question I'll punch a nun. Again. So I started an 11.1km run on the treadmill, at 2 degrees using the technique I use on the road; a slight lean forward, longish stride, heel toe-ing, arms at 90 degrees etc. I was running at a deliberately slow pace in order to analyse my stride. Here is what I found: The majority of the (unexpected) resistance came at the very end of the stride just as I am lifting my foot off. I figure this is down to the treadmill disappearing behind me, when usually on the road there is a more vertical take-off of my stride. A normally long stride is thus falsely extended and there is more reliance on an already over-extended calf muscle to flick the foot to catch the track up in order to push off. Conclusion: people who run with a longish stride may find that treadmill running is harder because of this, and may also find their calf muscles are being worked and stretched beyond their usual range leading to tired/tight muscles (additionally the front 'shin' area may become stiff with the effort of moving the toes back up from an extended position). Try running with a shorter lighter stride, increasing the 'pace per minute' rate instead of the stride length as you up your speed. Leaning forward, which I find has a positive 'toppling' effect on the road, increasing my pace and momentum, does not work in the same way on a treadmill. Conclusion: The treadmill maintains it's pace irrespective of the forward momentum you put into your stride and therefore you are wasting your effort 'pushing off'. The secret is to find a style of running that allows you to keep contact with the running surface for the least amount of time as possible. The lower leg therefore should be kept relaxed and you should be careful not to increase the stride length (particularly at the back). Instead concentrate on lifting your knees forwards and up and lifting your foot off as soon as possible. I found that running right at the front of the belt ensures that you are not reaching too far forward and instead develop an upward movement of the hips and knees. Keep you feet and ankle loose and try to picture yourself running on ice, where any big stride would make you slip. My lower calves were noticeably more relaxed, and interestingly my HR (measured off a Polar watch, not holding the handlebars) was a good 10% slower for the same pace. Also, as I increased speed and especially slope angle it took longer to feel myself breathing harder. Basically lift your legs up and allow the belt to pass under you. There, hope that helps.
