Our DCR Mt Greylock skimo race venue on the Thunderbolt is most likely the second-oldest alpine ski race venue still in existence anywhere outside of Europe: the ski trail was cut in 1934 specifically as an alpine race trail, and the first race was held in 1935.
Many other alpine races were held earlier elsewhere in North America, but they were either on mountains that no longer run ski races (e.g., Moosilauke, Rainier) or on ski trails that were absorbed into lift-served ski areas that no longer run races on those same routes (e.g., Cannon's Taft).
First, some caveats ...
(With gratitude to the historical research conducted by Blair Mahar, much of which is incorporated into this video: https://www.youtube.com/watch?v=0jl_WF6hM6c ... although additional material that was previously posted to a website has alas disappeared.)
The race on the Thunderbolt trail at Greylock has not been held continuously over the years.
- And not even close to continuously.
- The race has been plagued by low-snow cancellations (both back then, and now, alas), and also by WW II.
- Ski racing also took a long hiatus on the Thunderbolt, perhaps even for decades, when the trail was rarely skied for any purpose, competitively or otherwise.
- Lift-served skiing never came to Mt Greylock (although lifts were installed in 1974, yet not completed, but still there), except for some small rope tows.
- So competitors always had to get themselves to the top.
- But the self-propelled ascension was just the means to the end of the individually timed descent.
- The current format is a continuously timed loop of three ascents and descents with a mass start.
- But the core of the ski race is still alpine fixed-heel skiing. (Nobody uses telemark or splitboard for the race.)
The race course descent has not been entirely the same over the years.
- The original 1934 trail design had certain drawbacks, and a substantial portion was subsequently rerouted.
- The 1936 trail redesign also had a drawback that was subsequently rerouted, but this was only a small segment.
- And since the 2015 skimo race, the skimo race has omitted the top ~400' vertical (which is technically a highly skiable section of the Appalachian Trail, not the Thunderbolt), simply because of logistical issues.
- Then toward the bottom, the skimo race course often deviates from the Thunderbolt into the 1974 never-finished ski resort complex, also for logistical issues.
- However, that leaves the skimo race course with ~1,110' vertical (on each of three descents) in common with *exactly* the same race course layout as held starting in 1937, and ~800' vertical in common with *exactly* the same race course layout as held starting in 1935.
