Building for Old Pueblo

It's December 13 and Durango finally got some of the white stuff.  It's been the first year I recall that you could ride your MTB all the way to December.  It's been great, but oh man the Nordic and Alpine folks are jonesin.

According to my training plan, the build up for Old Pueblo begins today.  It might sound odd, given that I've done 4 White Rim rides in 2 weeks, that I consider today as the beginning of the's more of a seasonal attitude thing.  Growing up in Michigan, I was programmed at an early age to put on winter fat in the fall, and no matter where I live it happens every year.  Late October to Jan 1 is typically a time of weight gain, regardless of training volume.  Gimme some pie dammit!  This year seems to be different.  I'm super excited for what's to come in '06 and feeling fresh as a daisy at a CTL of 124.

The trainer is no way to start this build, so I opted for some interval work up Junction Creek road in the snow. 

Riding MTB in general reduces power output.  Combine that with snow and it becomes a judgement call whether to call it a skills ride or often required quite smooth form to avoid slippage, and going down was a real treat!

In between intervals 4 and 5 the shifting took a nap.  I have no idea why :)

Riding in the snow turned out to be a ton of fun, and I think I just discovered another strong point of these 29er wheels.  Hmmm....

Here's how it all turned out:

If you've seen my rants on wattage, you know why I'm doing this kind of stuff in December...but for the benefit of everyone else:  the short answer is that after a long season of long events (feb-oct), my power duration curve gets very, very flat.  That means top end power declines while long term power rises.  I view the winter as the time to rebuild top end power - a rather different take than most, but it works for me.  For MTB ultras, the trick is to have plenty of top end, and great long term power.  It's a difficult balance to achieve...but hell, riding a lot can make up for a lot training mistakes;)

Now that looks like a ride designed for a single speed!

Care to share the interval lengths and Pave?! I'd also like to request some smoothing next time!

Detail guy, eh? I had intended on showing what happens at different elevations, now is as good a time as any. There are 2 new files posted (in the files section of course); one is yesterday's ride, the other is a similar workout minus the snow at low elevation in AZ (one year ago). In fact, it was up and down the steepest hill we climbed last January, so you'll feel the pain when you look at the file. Links to the files:

Thanks - the files were interesting to look at. The 10% drop in power would be a real shock if you didn't realize what was occuring. One question - your max HR at elevation was about 3-4 beats lower than the previous file. Was that due to effort, elevation, or heat (or all of the above)?

Part of the power drop is explained by the elevation, but these files probably aren't the best for comparison because yesterday's was on an MTB in the snow - so that made power lower than typical. As for the HR - LTHR is about 171-172 near sea level and 168-169 at 6500'. It's best explained by elevation, but as I progress into L5 blocks (after 7-10 days) HR begins to get a little higher as the power goes up.
