Observations on sweaty self-abuse in the garage
This spring I’ve had a turbo set up in the garage with the High Baron on it, and I’ve been doing 2×20 minute intervals.
I haven’t ridden a recumbent seriously since August, and I wasn’t in the best shape then either. However, I’ve kept up my hundred miles a week commuting on a DF through the winter, and a fair bit of running.
I’ve never done structured training before for any sport. I’m aiming to do better at a couple of sportives (Etape Caledonia in May, Tour o’ the Borders in August) than I have previously from just commuting mileage. Call it an early midlife crisis…
Potential FTP / diamond frame performance
I’ve assumed my recumbent FTP could get as high as ~300W since I climbed Alp D’Huez last summer, on a normal bike, at an average of 291W – which took me just over 58 mins.
I was halfway through a week of big climbs and riding solo, so maybe that’s even an underestimate (I’m sure I could have gone harder with someone to chase!)
Either way, it’s some kind of line in the sand – if the physiology of recumbent riding was the same as diamond frame, I should be able to hit an hour at 290W in short order.
Rude intervention of reality
My opening session on the High Baron was three five-minute intervals, just to avoid destroying myself after six months of upright riding.
Optimistically I started at 304W, which dropped to 285W for set 2, then just 263W for set 3. I couldn’t push it any higher. Depressing stuff!
After a month, I could scrape out 2×20 minutes at 265W in exchange for much sweat and pain.
The interesting thing is that I’m challenging my cardio more than I expected. 20 minute intervals at 265W on the High Baron got my max HR up to 165bpm on the first interval, 170bpm on the second. In contrast, climbing Alp D’Huez for an hour at 291W on the DF only got my heart up to 159bpm (one factor that makes me think my FTP was actually quite a bit higher).
From “real life” riding I always feel “leg limited” on the HB versus “lung limited” on diamond frames (and I can hit 185bpm running, so I have the ability to deliver a fair bit more O2 than I’m using on either bike). In contrast, the turbo is definitely exposing a central cardiovascular limitation.
This leaves me with a bit of a puzzle over what sort of training I should actually be doing, not to mention a worry that riding the High Baron on a turbo might be structurally different from riding it on the road somehow.
The plan was to keep churning out my hundred miles a week of diamond-frame commuting at a low wattage, then add in two high intensity workouts each week on the recumbent. However, I figure that since my wattage can be so much higher on a different platform, maybe 20 minute intervals on the recumbent are not ideal, as they won’t really be working on the intended energy pathway?
At the same time I think this is an unrealistic way of reasoning. If the hardest I can go on the recumbent for an hour is 265W, then that’s my threshold power and I should be using that for threshold intervals on the recumbent (and go up to 290W for threshold intervals on my DF, if that was relevant).
Let’s not even consider whether 2×20 is the appropriate type of workout! 😐
Towards the end of the second month I started to get pretty tired (I think adding these workouts, simultaneously increasing my commutes as the weather improves, plus running, was having a cumulative impact).
I took a “rest” week (actually a hiking holiday) then did an FTP test loosely following the Coggan protocol – a short hard interval to drain your legs a bit (8 minutes at 301W) then a 20 minute all-out effort.
I did want to die, but I managed 288.5W (first ten minutes at 285W, second ten minutes at 292W) which gives an FTP of ~275W based on 95% of the longer interval.
This is still at least 15W shy of my diamond frame FTP, although I should probably validate that by riding the same test protocol on the turbo on my racer – but it’s definitely progress.
I’m not sure how much of this is improvement to my general fitness, to recumbent-specific muscles (hip flexors etc) that were lagging behind, or maybe just to my pain tolerance… but I’ll take it.
I now have five weeks until the Etape Caledonia, so armed with this FTP estimate, it’s time to think about what sort of training to do – probably don’t want to turn up at an 80 mile ride having only done 20 minute turbo intervals, for starters!
Etape Caledonia -4 weeks
Four weeks to go before the Etape Caledonia, which is my “B” event (I mainly entered it so I would get my recumbent out of the garage before June!)
As I haven’t ridden the High Baron for more than an hour since last summer, I decided it would be a good idea to [URL=”https://www.strava.com/activities/540340314/”]ride the route[/URL]. Partly to check for any corners that I can’t take at full speed, partly for the long ride training aspect.
It’s 80 miles / 130km but only 1,200m / 4,000ft of ascent. It took me 4:10 moving time (19.5mph average) with just under 25 minutes of stops (half of that was getting breakfast, the other half was watering the verge… FFS!)
I felt my power was pretty poor on this ride, but I think my expectations were unrealistic considering I had no taper and didn’t eat any carbs before heading out / only had a light energy drink on the bike.
Interestingly it felt like my efforts at short rises were noticeably stronger (even though this is above-threshold wattage) whereas I wasn’t able to ride anywhere near my threshold otherwise – the sustained central portion of the ride I was just putting out 200W, and the long flat finish I was right down at a 160W average.
There are a few niggles with the High Baron to sort out, then I think I’ll repeat the dry run in two weeks’ time. That will give an ample taper into the event, and we’ll see what happens!
Tour o’ the Borders is the goal, but the Etape Caledonia route is also quite a bonny one. It will be fun to ride this event in its own right
