March of the Pigs

Quest of the obsessed might say it better.

Time for some geek talk, it's been awhile since I mentioned stuff like TSS, the training manager and the like.

So what does one do when GLR is in the plan but fitness is at rock-bottom post surgery?  Time for some planning, that's what!  It doesn't take a rocket scientist to figure that an event like the Grand Loop requires massive endurance, a functional gut, solid technical skills...and about 20 other things I could mention.  To nail the first (and to an extent the second) the training manager, as usual, comes to the rescue.  Knowing a bit about the demands of ultra events, how I respond at certain CTL/ATL levels, it's possible to map out a plan projecting TSS forwards.  I do this in a spreadsheet of course.  It's turned out to be darn close in reality to what I had mapped out back in the winter when I had all those long hours of no riding to fill my days.  Here's the pic, click for bigger.

This is one serious build, even by my standards.  Coming from a CTL of 57 in Dec to 150 last weekend - that's a march of the pigs :)  Note the occasional big spikes - that's characteristic of ultra cyclists.  Days of 500+ TSS will do that to your CTL curve.  Even so, the upward trend is more or less constant over the long haul.  Those really big spikes tend to incur some hefty recovery penalties.  In some regards, this makes ultra cycing ideal for the working rider who has lots of time on the weekends but not so much on the weekdays - I couldn't train like that all week long every week or I'd be toast.

This is a bit of an experiment.  I've never done an event anything like GLR - the closest would be a 24 hour event.  GLR is more like 2 24s and a hundy strung back to back.  I estimate TSS to be about 2300 for the event - that's more than 7 days of full-tilt racing last summer in TransRockies.  But with this tool I have confidence that endurance is right up there at or close to PB levels as I'm about as high CTL-wise as I got last year.  The difference this time around is I never got smoked in the process, and that's a good thing.

Last week saw very little training, so TSB shot upwards in a hurry (5 day ATL TC).  Starting this week at +54 TSB, there's room for a 1000 TSS week while staying positive TSB the entrire time.  How about that for a "taper" week?

So there are all my training ideas in a picture.  Make sense?

That's quite the CTL dump after GLR. Got it in you?

Geek!

Considering the downward spiral you're on into endurance racing oblivion (racing alone in the middle of no where for days on end!), it is inevitable that all the trappings of techno-geekiness should eventually fall by the wayside and you will become a gray-bearded old fogey grumpily eyeing the shiny new toys the next generation rides forth on.

This retrograde into retro-grouchiness will be fun to watch; join us, join us :-)

Oh and good luck!

LOL Ed! Sometimes I lean that way lately. Shhh, don't tell anyone.

Lynda - not a chance. That part isn't mapped out yet. ATL will be a better marker for me in BCBR than CTL.

So, if you don't have a power meter on every bike that you train on, how do you know where you really are in relation to your plan?

Good question Dave.

Intensity Factor (IF) is a measure of how hard the ride was relative to your functional threhsold power. For example, an IF of 1.0 for one hour is all out, .9 is pretty hard (tempo pace), .8 typical for long hard rides, .65ish is recovery and so on. Having ridden with power meters for 6 years now, I can guess the IF really close to actual for any given ride.

So, for rides I don't have a PM on board I calculate TSS based on my IF guess: TSS = IF*IF*duration(in hours)*100.

Right now I've got power on 2 MTBs and one road bike so I still get a lot of data, and that's important to do periodically cause your "guestimator" might get miscalibrated. This method will only work for those that have a power meter. To always guess without any calibration would likely lead to enough error that you'd be making incorrect training assumptions/observations based on flawed data.

Thanks Dave. What PM are you using on the mtn bikes? Powertab hubs? If you were buying one today, what would you buy?

Yep, I'm using powertaps. There is no perfect solution for power from an MTB - all available systems require equipment concessions, and of the systems I've seen (SRM, Ergomo, Polar and PowerTap) the PT is the only one I'd trust to produce reliable data.

I wouldn't buy one today. There are some strong rumors in the mill that PT is working on getting a disc compatable hub out - that would be the holy grail...well much better anyway. The current PT offerings are not disc compatible so you have to run v-brakes. For training that's generally OK but for racing I prefer discs over data.

Be sure to bring this up with Lynda. She's used them all but Polar and might have a different take.

Huh? Do you really ride, or just come up with squiggly graphs to scare the competition?
You're nuts (in the good/smart way).

Ah good stuff! This is what I come here for. I think you can get away with guessing but you have to be pretty darned dialed in and honest about it. If you do a lot of group rides you'd be better off just picking a number (72?) and always using that as your TSS/hour on a ride of 3 hours or less.

I bet you could get an interesting distribution for TSS/hour as plotted versus length of ride. So for 3-4 hour rides does it drop from an average of 75 to 68? The window of 4-5 hours another step down?

Geez. Now I'm really confused! All these charts and graphs and calculations. Can't I just ride my bike? ;-)
