Run vs Cycling Issues

  • Profile photo of NZRUN Archive

    Haven’t run for about 8weeks now but have been riding a hell of a lot with the mind frame that once my problem comes right i’ll still be plenty fit and be able to transition into running fairly quickly. I know a lot of people go between codes all the time and was wondering if there are any issues created by cycling that will effect me negatively when I try to run again?

    Ive been riding a mountain bike at around 300/400km a week and I’ve already noticed the quads get demolished and the hamstrings take up a lot more work
    be interesting to hear from anyone who has been forced to do this before and how they came out of it, or duathletes/triathletes who are doing both simultaneously.

    Yep, running is obviously a lot more weight bearing than cycling. So if you’ve been off your feet for a while, just be aware that there will be an obvious transition back to that as leg muscles get used to taking up a bit more of the slack.

    Also, cycling is very much more inclined to be not as constant as running in aerobic effort. Headwind v tailwind, uphill v downhill coasting. Very evident in HR profiles between the two modes of transport. So your longer runs will be a bit more tiring than the cycling efforts where you get to cruise intermittently.

    Hey Jesse it would be great if someone had a direct line upstairs because the great Jack Foster would have a few thoughts on this.

    I’ve been on the bike tons this year due to getting injured and certainly you need at least a bit of running to maintain the biomechanics of runnning. Tend to feel very clunky and not efficient once you get back into it, but with a mix of the 2 life is pretty good, doesn’t seem to hurt Al Brownlee at all!

    Hi Jesse,

    It depends on how Bike Set up how you load your muscles. If your seat is set far forward you will load your quads more. Automatically we use our quads more by pushing down on the pedals. Also we don’t extend the legs on the bike, so the motion is still different to running.

    I used to be able to knock out my fastest 5kms on minimal running and only a bit of intervals plus a lot of cycling.

    When I ran more I didn’t run as well until I dropped the volume of the riding, as my lower back and hips were getting stiff from my cycling position.

    However, I don’t think you are going to do any damage by riding and not running. You will notice a little difference in strength (run vs cycling) and also from conditioning. When you start running it feels a little harder, but the flow comes back easier.
    This year I was tore my calf muscle and did a mix of aqua jogging and cycling. I was only doing 60 minutes or so hard on a windtrainer, but when I could run again after 2 weeks was back to 130km+.

    At the end of the day riding is going to help you stay fitad sane and then you will be able to get back into form easier.
