Tires, Cycling, and the southwest.

Yesterday's flat was most likely caused by something called a "puncture vine" seed, also known as "Mexican sand bur." It's a noxious week that grows very well all over the place.

These pretty little vines put out little yellow flowers, and then they produce a small fruit. The fruit dries and produces four seeds known around here as "goatheads".

Goatheads have long, stiff thorns heading out in 2 directions, and they lay in a way so that no matter which ways it lands, there's one thorn sticking up. They're about 1/4 inch long. Seeds like this spread by getting caught in the fur of animals and being carried that way. They also blow around pretty well.

They are EVERYWHERE. I walked through the desert in a pair of lower-end sandals the other day, about 700 meters, and by the time I was done the entire bottom of each sandal was completely crusted with them. They covered the entire bottom.

Goatheads are otherwise known as "MOTHERF&$%R!" by the people dumb enough to walk around barefoot, or those who've flatted out for the second or third time when they've ignored the advice of the locals.

You see, the really great thing about living in Albuquerque is that is rarely rains here, so there's lots and lots of time to spend outdoors. We're a mile above sea level, which is good for training, and the humidity is fairly low, usually less than 20% but almost always less than 25%.

Last summer we had an unusual rainy season, and on some of the days the humidity was a whopping 50%. Boy, did we whine! We (meaning denizens of the Burque) walked around saying in our whiniest voices, "Oh, my gosh, it's just so HOT and so STICKY. Oh, my gosh, when will this end?" But anyway, I'm rambling.

Even the insane wind is not al that bad. It's good for training.

The bad thing about Albuquerque is the occasional sand storms and, of course, goatheads.

So we occasionally get people who are new to the area, people who like to run or do triathlon, and we remind them of three things:

1) Hydrate, hydrate, hydrate- this IS the desert!

2) you'll need about 500 spf sunscreen, and

3) you'll need some super thorn-resistant setup on your bike.

This usually involves a type of tire with Kevlar in it (Specialized Armadillos or Bontrager Hardcase), sometimes a thorn-proof liner, and some sort of sealant like Stans, that seals punctures and allows you to air up the tire again if it goes flat.

With this setup I've never gotten a flat.

When I bought my new bike, I was talked into getting something called Gatorskins. POP! PSSSSSSSSSSSS, a flat. As well, I didn't have any sealant in them. I did some searching, and read some cycling forums and there's a general consensus that Gatorskins may, indeed, be absolute crap.
So I will endeavor this week to replace the Gatorskins with some decent Kevlar tires.

Anyway, if you ever decide to do a race here, keep this post in mind. You may think you've got evil tire-puncturing things where you live? Well, maybe you do. They grow wild here.

You've been warned!
