Yeah, I’m not exactly young or the healthiest, being 55 and 30+ lbs overweight, but this spring, my zone 2 power kept going up (I mostly use HR to stay in zone, for this reason), and I suddenly started crushing my Strava PRs set back in 2017 and 2018. And I don’t use TR software, but I do credit this forum and the TR podcast with a lot of my success, because I had all the usual struggles at one time or another in the years before, and have gained a lot of knowledge here. My intensity is mostly done outside on my mtb using HR, sometimes on the road for all or part. It’s very flat in my county, but the county just north of me has “hills” (I’m in FL), and I have lots of Nat Forest 5 miles away, that I can ride for days and days.
I’d probably go with consistency at the top of the list. I ride/train all year and I push pretty hard on intensity days, pushing my TTE a lot. I do 3 weeks on, 1 week easier, I do either 2 or 3 zone 2 sessions (1.25 to 1.5 hrs, @ whatever IF feels good) between Tues & Thurs, and usually ride outside Fri, Sat, Sun, usually with (1) in tempo 2+ hrs (bottom half of z3), one in SS for 2ish hrs, and then usually I need an easier ride on Sunday if I’m not doing a no-drop ride that our IMBA chapter puts on (that is like sprint for 10-15 mins, wait and rest for 10 minutes, sprint…). I rode 2:08 Saturday and was in z4 HR for 1:50, on sandy singletrack with punchy climbs.
If I feel like I need to do some VO2 intervals or specific threshold stuff, or check my FTP, I do it inside (because I can measure power) maybe on Wed or Thurs, and then ride another easy z2/3 day outside over the weekend.
On my easy week, the Tue-Thurs is usually an easy 30 min spin and a 1-1.5 hr z2 ride, then my regular Fri-Sun schedule, unless I’m feeling like I need more rest. Not too long after covid hit, I found I had worked myself into an overreached (or overtrained?) hole that it took me a while to dig out of, so I’m pretty conscious of how my legs feel. Oh, in 2022, a big part of digging myself out of that hole was I started doing zone 2 rides…like 5 days a week…I was buried working 6 and 7 days a week for months, and only had time to ride outside once a week, and couldn’t sleep, so at some point decided if I was going to be awake at 4am every morning, I’d get on the bike, and started at 30mins, saw something (Inigo San Milan?) that said the benefits start at 0:45 so bumped my rides to 0:45, then started seeing the power rising at the low end of my z2 HR, and eventually ended up averaging 1:15 to 1:30 per day. I retired at the end of that year, so switched to riding outside the 3 days each weekend, with the other days at z2.
I keep saying I’m going to get a better inside setup and join TR, but I’m afraid it’ll take the fun out of what I’m doing (I don’t race). And I need to work on climbing more, but I’m hoping weight loss will help with that…so far so good.
