I'm excited this came across my feed. I used to mountain bike, but I don't anymore. I still follow your style of training because I feel it's more functional than what the other programs are putting out. I'm also 48 going on 49 this year and stopped training as much as I used to because I was feeling broken. I also have a physical job unloading freight at a grocery store. I don't see most online workout programs detailing workouts to 40+ people since most of the programmers are still just turning 30 to 35. I will definitely be buying the 40+ workout program.

I like that training idea, thanks!

If Eddy Merx was still competing his famous maxim “Rides Lots” would definitely be supplemented by strength training. I’m pushing 70 and doing more challenging trail rides than 20 years ago. I credit this to Catalyst Pedals, mid-foot position pedaling, much more standing pedaling, and mountain bike specific leg strengthening (especially hip extenders: glutes and hamstrings to maximize flat pedal efficiency). All of which is due to your pedals and programs. -Cheers and thanks for helping extend my mountain biking regime another couple of decades. That said, I have a very different approach to VO2-Max and Lactate Threshold Training. Sprint Interval Training as originally demonstrated in the 2005 McMaster University study, and subsequently replicated with a myriad of modifications dozens of times since, proves that the anerobic based Sprint Interval Training is most efficient form of aerobic training and mitochondrial biogenesis. (Aerobic adaptation occurs during the relatively long total rest periods between repeated sprints.) Of the three traditional lactate optimization methods, I find that fairly conventional HIIT (High Intensity Interval Training) with the high-intensity period at about 85% of VO2-Max and the low-intensity period about 60% of VO2-max is the most effective for me. To minimize lumbar stress, I perform HIIT on a steep paved rolling route on a road bike. And yes, I also run Catalyst pedals on my road and gravel bikes. It all comes down to: is VO2-Max and Lactate Threshold adaption tissue specific or a centralized systemic process? Since the majority of adaptation occurs in working motor units, I believe it’s the former. The concept of local adaptation has been reinforced by several one-legged pedaling studies.
