I thought I'd share some thoughts on training so that you can all tell me how wrong and stupid I am and how I'm doing it all wrong.
First of all, the limiting factor is whether I actually enjoy doing something. If I don't, I won't stick at it. So this limits me to my weekend rides plus a couple of in-week one hour turbo sessions, which is what I've been doing.
Second - a target. Most training needs a target. I actually do have one: I'm planning a ride in France in June including a couple of HC climbs (each just over 1000m in just under 20km, with steep bits) . Target is just to be able to do it, time/speed isn't important. Misery reduction is really the aim.
So this leaves me with a Saturday ride and two turbo sessions. The Saturday ride is whatever I want to do at the time, typically 80-160km generally as hilly as I can make it. I could always tweak these a bit to suit training requirements. On Saturdays when I'm busy I get up early and do a 2hr+ turbo session. Again, I could change this if I can come up with something better. Often this is a simulation of a big climb like Ventoux, which I do in a big gear to keep my cadence down (70-ish) as that seems more realistic (my turbo claims to be able to simulate 16% gradients, but I don't believe it).
What I've been doing on the turbo is just an hour of something hard. Over/under FTP intervals or 3x10min sweet spot. I figure I get enough Z2 endurance tootling when I'm outside. Also, getting on the turbo for an hour and not flogging myself feels like it's defeating the object.
I work in the office a couple of days a week, and I could always commute (relatively flat 10km each way) to get some miles in but as I actually dislike doing that, I know I'd be unlikely to stick at it. But I could give it a go.
With the new year coming up, maybe I should switch things around a bit. So, given that I don't have huge latitude to change things - how wrong am I?
I did exactly this in 2023, training for the Maratona, based on 2 outdoor rides a week and 2 turbo sessions. All went a bit wrong as I caught COVID in Italy, but these were my principles in case it helps:
1. Worked on principle of of time in saddle and Training Load (or TSS if you prefer)
2. Adapted a 12 week Wattbike training plan (can send to you or post here) to work our rest weeks and tapering
3. Did mainly Threshold intervals (or similar, eg sweet spot, under overs) on the turbo - in retrospect could have, perhaps should have included VO2 max intervals
4. One of my outdoor rides was usually hilly
5. Increased length of long "Zone 2" ride each week
6. Used a power meter and HR monitor and tried to make sure that 80% of my riding was Zone 2 or below each week and in each training block over all
7. Used zwofactory to build interval workouts, and then
https://flux-web.vercel.app/ to ride them - both free
8. Pulled all the data from indoor and outdoor rides into intervals.icu to look at progress, monitor time in power zones, track fitness and use the calendar
9. The intervals.icu forum has got some interesting training threads too
But I reckon you could go out there tomorrow and do the rides you are planning with no problem. Will you enjoy it more if you are fitter? Probably
