Quoted message said:I had a question: I will be going out three or four days early - what
regimen would you recommend to maximize my acclimation to the
altitude?
Acclimatization is hard to predict. I have gone to 9000 feet and thought I
would die. I have gone from 300 feet (where I live and train) to 12,000 and
felt pretty good. It varies from person to person and for an individual it
varies from time to time.
I like to climb mountains and have also done the DR 3 times ... here are
some of my very general conclusions based on a near sea level start.
1) Many people can go to 9000 feet for a day most of the time without
suffering from significant altitude sickness which means headache and
lethargy at a minimum.
2) Sleeping above 6000 feet may be a tiny bit troubled the first night or
two by elevated pulse rate and uneasiness - take a Tylenol PM or similar.
3) Everybody feels a shortness of breath at 9000 feet and pretty much always
does, even when acclimatized.
4) Symptoms like headache usually take 4 to 6 hours to manifest - flying
into La Paz, Bolivia at 13,000 feet I felt fine getting off the plane in the
AM but felt like I had a pretty good hangover by bedtime. You won't be at
elevation long enough to actually get sick.
5) Acclimatization takes about a day per 1000 feet.
An absolute minimum prep for the DR for a healthy, fit flat-lander would be
to have two full days before the ride. The first day I would ride fairly
hard and try the elevation out - do Ebbetts Pass because it is the best
ride. Sleep at Markleeville or higher. Rest the second day with maybe a
casual ride to the hot springs for a soak. Very little of the DR is above
8000 feet and almost no time is spent above 8000'. Altitude sickness is not
a very likely problem.
Quoted message said:I will have ridden about 2000+ miles at that point - and have done
back-to-back centuries and ridden rides like the Wright Stuff Century
(for those who know it) easily in ~six hours.
2000 miles of prep in what time period? After completing 5 passes with my
friend Mark in 2003, I asked him what his training regimen had been and he
said "Oh I did about three hundred miles." "A week?" I asked. "No, total
this year." I think he spent the rest of his time working at a desk and
changing diapers.
The Death Ride mostly has to do with endurance and pacing. Go slow, eat
before you get hungry and drink before you get thirsty. If you are climbing
and can't chat with the rider next to you, you are going too fast. You have
plenty of time so don't get in a hurry, especially early in the day. I don't
think I have seen a rider actually succumb to altitude sickness and fail. We
all gasp a bit but who wouldn't after climbing non-stop for 2 hours up
Carson Pass?
High and low temperatures are a big challenge. You can have frost at the
start and I have seen 110 degrees f displayed on my bike computer. Hail
storms, lightning and heavy rain will usually stop the ride. Watch out for
