I am 57yo, have been cycling for 3 years, started crit and road racing in January. Prior to taking up cycling I had no fitness/aerobic activity since high school but have been happy with my progress so far. I train about 10 hours a week and believe I will continue to improve by using the Friel training plan I used this year. Question: would good use of a power meter bring on signifcantly quicker gains than well executed traditional training methods?
