I could put this in the Tri forum but does not get as much business. I have ask this before in different way but will try again. I come from a 35 year running background and I am still a runner over cycling but the last 5 years averaging a bit over 4000 miles a year as a took up cycling more serious. At first my it helped my running but now I think it is really hurt it. My endurance if great resting heart rate still 40-44 can run but really it feels awkward now and my stride never seems smooth. I just fight trying to maintain form. Up until 2 years ago my usually running pace for training was 8:30-8:50 and if tired 9 minutes for maybe 7 mile daily run. Now I am training and have trouble keeping a 9:00-9:30 pace. I trying even do surges and pick ups and if I am lucky I can run maybe 8:15 mile tops. The crazy thing is I can easily go out and run a 10 mile run distance is not problem.
I realize I am a do over train but keeps the weight off but I seem to have lost any speed I ever had, which was not much but this running 9:15 to 9:45 miles is terrible. At 53 I way past my best days but I seem to be slowing down faster than others. At this point I think it is completely the bike. Do any of you have experience with this transition from running to cycling? Any roadies who did/do both and have feedback on this? I google stuff and do not get much. Most will say cycling is good for running to a point...........but maybe I have past that. Finally I may very well be better at cycling than running. I am no racer but I can manage a solo century in flat Illinois in close to 5 hours on a good day ( 19 mph 5:15). I wonder if I trained the cycling legs too well. At this point I love ride more than running but runner just take less time and you can do it year around. I do ride year around and outside in the cold but cycling is less in Dec, Jan, Feb. The less cycling these months does not seem to cause my running lets to snap back either. I wonder at this point if I have built up enough cycling legs riding maybe only 1 ride a week keeps them going. I hope someone has insight on this I cannot find much.
