I do about 3.5 hour per week with a maximum…MAXIMUM of 4 hours a week on the bike, Im not training for IM or HIM, I have access to a closet 40k loop, i soft pedal to the loop, then hammer as hard as I can for the loop 3 times per week for a total of about 83 miles a week. I dont do long rides or recovery rides, just FTP type efforts on the loop.
If I only had 4 hrs per week that is exactly what I would do also.
I tried this kind of all-hard training, and I was toast after 3 weeks, with the running and swimming on top (also done hard, granted.)
If biking was the ONLY thing I were doing, it might be doable, but with SBR, if you’re actually going your near-max for those 3-4 rides, you’ll be toasted. It sounds good in theory, but in practice, you’ve gotta be in near-race shape to pull that off, and I doubt you’ll last for more than 4-5 weeks if you’re still swimming and running seriously as well.
Ive been doing it for 39 weeks, no problemo, I think that the shorter workouts afford me more time to recover. Also, I dont swim, Im not training right now, just working out, enjoying being fit enough to do other things I like (getting back into mountaineering) so im happy with sub hour 40k TTs and sub 40 min 10k’s.
I really train about 8 hours a week and about three weeks from now, the bike will get scrapped because of job stuff, so ill either add 3 hours of running or 3 hours of gym time. we’ll see.
I do some runs on tired legs, but the cycling nevers suffers from fatigue, I have more than enough recovery time between rides so theres absolutely no issue there. The rest is just 40-50mpw running. I jump in some 5ks and do some hard workouts, but since I really dont have a race coming up, I just train, yeah, some days are sluggish, but 100% of the time, whenever I have a hard day, the following day kicks ass so I dont sweat it, Like I said, not racing right now, just enjoying working out without pressure.
FWIW, I started doing this after resisting Flecks advice for a long time, I was piling on high milage stuff, not having fun, getting burned out, injured and pulling off shit 12 hour IMs. Now im actually training half as much and seeing better results and enjoying myself. At the moment, I have it all.
