So here is my deeply scientific N=1 study into what happened when i didn’t ride a bike for 6 months but ran 35 miles a week.
M50 74Kg. Previously FTP about 300W on about 6 hours per week. I had to give up cycling totally due to suffering pudendal neuralgia but i managed to keep running and i upped this to 35-40 miles per week. For calibration: I can do 5km in 19.30 and a 3:45 trail marathon.
This week i went back to the turbo and did a ramp test at 230W.
So running keeps you fit and sane but you still lose an absolute ton of cycling watts!!
Time to get busy again. I hope this adaptive training lark works…
