Only for the first three days until I get acclimated.

I doubt the challenger lives above 8000 feet anyway. That's pretty much my threshold those first three days. We would both be sucking wind above 12,000 feet regardless.

Climbing and time trials are my strong suit. It's flat as a pancake down here in NOLA, so you have to pedal all the time, often exposed to a headwind. You stop pedaling, you stop rolling - just like long climbs in the mountains.

Road descents no prob. I can rock 50+ mph. Single track downhill - pass the Pampers. Done it, hate it.
