Weather & Altitude:
The weather will present an unpredictable challenge
in itself. Grande Cache is at an elevation of 4200ft and is subjected to
the unpredictable weather of the Rocky Mountains. Summer time temperatures
range dramatically but generally reach daytime highs of 17C to 22C and night
time lows of 8C to12C. Precipitation varies as well but tends to be dry(er)
in the months of August and September.
The mountain summits will be approximately 7-12degrees Celsius cooler
than the valleys and 4 to 7 degrees cooler then the temperature in town.
Strong winds always prevail on the mountain summits. Altitude will be a factor,
and while acclimatization is not necessary a 3-5 day adjustment period is
recommended for maximum performance. Also, it is advisable for your crews
to make available to you light rain gear and dry clothing at each aid station
should you need it.
