Weather in Wyoming can vary
substantially, both with time and altitude. Riders
should be prepared for temperatures in the upper
elevations to be somewhat cooler than in the lower
elevations. At higher elevations, there may be hail,
sleet and/or snow. Be prepared!
As a general rule-of-thumb, temperature will decrease
about 5 degrees (F) with each 1000 feet of altitude. So
expect the temperature at Libby Flats (10,847 ft) to be
about 18°F cooler than what's reported in Laramie (7,284
ft at the airport), all other things the same. Expect
temperatures in Albany (the start/finish line at 8,400
ft) to be about 6°F cooler than Laramie.
Daily temperature differences are also greater in this
area than in others. Expect about a 25°F temperature
variation from the coolest to warmest temperature over a
24-hour period (again, all other things the same).
Temperature swings between sunny and cloudy conditions
are also greater at higher altitudes.
Factoring all that in together, it's likely to be a bit
warmer at Libby Flats in mid-day than in Albany in the
morning, as the normal daily temperature rise will
probably more than offset the temperature drop due to
altitude. But...Historically, thunderstorms are expected
after 2pm in about one of every 3 or 4 days at the
higher altitudes of the road race course, so prepare
accordingly. At higher elevations, there may be hail,
sleet and/or snow. Be prepared! |

Real-time weather information sources
are generally limited to sensors located at the Laramie
airport, approximately 18 miles east of the eastern-most
portion of the road race course, and at a similar
altitude to the lowest point of the road race course.
