Training & Nutrition - wow running does not equal cycling

I have been training for a 25k run in march... i also got a bike over the winter that i rode on a set of rollers over snowy months for 20-30 min at a time with the intent of getting into some road and cyclocross rides this year.

I have a chronic injury to my ankle that i have an MRI scheduled for monday... i thought i had it licked this year as i have been running 1/2 marathons each year for the past 3 years, following which i have to take 6 mo off of running to heal.

rode 15 miles today, and my legs are whooped. :lol:. crazy that i can run 15 miles but can't ride em. It's a different kind of tired... more in the legs less in the lungs, but i loved it (first warm weather ride of the year). Guess i will be swapping my weekday/end runs for rides for a few weeks till i meet the surgeon.

thought id share for any runners who think they can hop on a bike and pedal with the hardkore doods... that is all:notamused:

Don't worry, I can bike 50k at ~30k/hr but can barely run (jog?) 5k. Yes, totally different :)

The problem I have is, I can cycle almost any distance, so my cardio fitness is high, so whenever I decide to start running again after a layoff, I head out and "think" I feel great and end up going too fast, which usually results in me barely being able to walk for the next 2 days with the muscle soreness :D

The length-tension relationships are all wrong if you expect direct transfer to running or vice-versa.

yeah they use complimentary muscles, etc.

after injuring my achilles a couple years ago I was advised to ride a bike during my rehab and that helped a lot.

are you a myofascial guy? thought i saw a posterior chain reference in another of you posts... and now length-tension... what's next? Tensegrity spheres? (just yanking your flank...)
