Eddie B pushed that interpretation in his book 25 years ago, but a lot of folks still ride their Steady a lot easier than SST.
My thinking about this has evolved in the past year. I went from many years of LSD base training where the S was pretty darn slow compared to SST work (under the direction of very qualified coaches but with terrible results). Then I got a PM and hardly did any long rides with an emphasis on focused shorter SST/L4 work for base building. A search of these forums shows how hard I've pushed that approach. This season I had a bit more CTL focus and have really benefitted from riding at least one longer ride per week on the following condition:
- The long ride should only be as long as I can maintain good focus and keep my intensity at least in the upper reaches of L2 and preferably finish the ride with an IF in the L3 range. I shouldn't be absolutely trashed after this ride, if it costs me several days of recovery and missed training sessions then it was too long.
IOW, my current thinking is to ride at least one ride per week that's long as long as it doesn't degrade into junk miles or cost me future training sessions. For some folks that might be an hour and a half ride. For Cat 1/2 riders regularly racing 100 mile events that might be four or five hours of solid pacing, for a pro riding grand tours that might be longer. The key is to limit the ride to what you can do with good intensity and still recover well enough to stick to your weekly training schedule.
My late race performance has improved with this approach. I've only done one of these Long Tempo rides that exceeded five hours and a few that were four plus hours long. I almost always ride them alone so I can ride my own pace and I worked up from "long" Tempo rides that were approximately two and a half hours long this spring adding time and mileage as my fitness improved.
It doesn't surprise me that high category riders do a lot of rides that are really long compared to other folks but I suspect a lot of them are holding pretty good intensity during those longer sessions. And I'll bet they're not just cruisin' around with a bunch of friends sitting on wheels most of the time and maybe hammering the hills which seems to be the norm for most weekend group "training rides" around here.
YMMV,
