I’m 41, riding for 15 years, 65kg and currently around 5.2w/kg. I only started approaching 5w/kg last year. I was not an athlete in high school (marching band) and did not show any special athletic potential. I think the biggest contributors are:
1 - Weight management - Hitting 5w/kg is much more achievable for me at 65kg (need 325w ftp) than when I was at 72kg (would need 360w ftp.). Tracking calories and slowly dropping from 72+kg to 65-64kg over 3-6 months allowed me to retain most of my power and not fell super hungry or lethargic. I am now eating a balanced, low-calorie density diet that includes most of the foods I enjoy. The low calorie density lets me eat a lot of volume and feel full while hitting the calorie targets and maintaining or loosing weight slowly. I phased on small changes over time, allowing them to become habits and a new life style. ‘Dieting’ doesn’t work if you go back to the habits you had at the higher weight. They’re the habits that got you to the higher weight. Sustainable life style changes are needed to maintain the lower weight once you’re there.
2 - Consistency - I ride 7 days a week now except for special circumstances. 2 are active recovery and I swap them around or shorten workouts depending on whats going on, but I almost always ride for some amount of time every day. 30min is better than nothing, 45 better than 30, 60 better than 45. Riding 5 days a week, with some swapping depending on life events wasn’t consistent enough for me. Also the more indoor riding I do the stronger I get… probably due to increased consistency and efficiency.
3 - Volume - I am normally between 10 and 12 hours a week. TSS is 600-700 for loading weeks. I would not say my volume is very high, but I think a certain amount of volume is required. I don’t think 5-6 hours across 3-5 days would cut it but 20 hour weeks isn’t necessary for me. I have been doing TR Low Volume plans, which is about half of my training load, and for SSBI/II do the 3 workouts on Tues → Thurs and that also worked for the first half of SPB, also LV. I wasn’t recovering quickly enough in the second half of SPB to keep doing the workouts on consecutive days and some ideas how to fit them into my schedule with Z2 or Z1 rides in-between for the next go around. Mon / Fri are normally Lazy Mountain (Z1). Saturday is either unstructured outdoor ride, unstructured Zwift ride or event, or sometimes I do a TR workout that makes sense based on where I am in the current phase followed by unstructured riding. Sunday is also unstructured outdoor ride or Zwift ride or event.
4 - Structure - Last year I was hovering around 4.9-5.0w/kg from a combination of high volume and intensity, but with no structure and plenty of ad-hoc zwift races, fondos, and group rides. Starting with TrainerRoad in the fall added structure and now I am much more picky about choosing which zwift events to take part in, and the ones I choose to take part in make sense for my current training phase, planned training load, and how I’m feeling. I find it very easy to go too hard in rides and races leading to multiple days of fatigue and will now pick events that I can recover from or make sense in the context of where I am in a TR phase. Structure and being fresh to smash the TR interval workouts has helped me set multiple 20min power PRs since last September.
5 - Recovery - Probably like many of us, prior to TR I rode too hard most of the time and not hard enough when I should have been going hard. And I was very bad about recovery during the week and as part of a cycle. I do Lazy Mountain in erg mode on Mondays and Fridays to force me to get in a couple of active recovery / easy days. And I follow the full recovery week in the TR plans in erg mode to also force me to get some recovery. I enjoy those workouts / weeks less than the SS,Threshold,V02 workouts, but I think the results have been great and it is nice not to feel tired and fatigued all of the time.
6 - Mental Attitude - I think a positive mental attitude is super important. I try to go into each structured workout excited to just smash it. If I back pedal or have issues during the last interval I don’t consider that a failure. It just means that I’m pushing myself and challenging myself to get stronger. Over/Unders are hard, they are supposed to be hard and struggling at the end just means I have some lingering fatigue and/or have my FTP set correctly. VO2 is a weak area for me, so having issues with the last couple of intervals just means I’m pushing myself and trying to develop weak areas. But I also need to be introspective enough to determine if my FTP needs to be adjusted, or that I need to tone down v02 power targets, or I need more recovery time instead of just smashing myself into a wall over and over.
