Highest gravel Grinder in the USA , Would you do this Race / Ride ?

I imagine the scenery is beautiful and a challenge is a good thing, but that's a lot of miles and climbing at elevations over 8,000 ft.
It would be very tough on flatlanders and old guys (like me).   
(or maybe you want to make it exclusive)
 
Would it be possible to arrange the route as loops so folks could bail on one or more sections if the full course proves to be too much?
(you could give the route options creative names like "Twinkie" up to "Hercules"...  )

Salidagravel--sounds similar to the VaporTrail 125 route that I just looked at although they spend some distances on the Colorado Trail and Rainbow Trail. You thinking of doing Marshall, Monarch and Hancock passes?
I agree with levity...150 miles is a BIG day at that kind of elevation with ~11,000' of climbing (that I estimated from your profile picture). I also suggest additional, lower mileage loop options to make it more appealing to a wider audience.
Thanx for asking.

I live in SW Kansas but enjoy the get-a-way to Salida. I observed some nice gravel while driving in that area. I would like to learn more about gravel ride in that area if the info is available. I do agree with the others that replied for some shorter options because altitude and distance will take a toll eventually. However, I would like the challenge of riding my cross bike in really secluded and beautiful mountainous terrain. I hope to ride the west side of Cottonwood Pass from the lake. Are there better loop/climb options?

I live in Colorado Springs and I'd do it. I'd love to see the route. \n \nCroz

I would do it if I could divide it into many many days of bikepacking and picture taking.

This is a pretty old post, but wondering if you ever figured out a route? This sounds kind of awesome/total destruction of my body (but thats why we're cyclists). 

Thanks! 

I'd offer a 75 mile route as an option. 150 miles on gravel somewhere in the Midwest is a big day even for very fit gravel racers. At that elevation, few riders would finish a 150 mile ride. \n\nHave you done the 150 mile route yourself?

Longest ride I've been on was the triple bypass, done that three times, not on gravel and 'only' 126 miles. Agreed that 150 is a lot, especially here in Colorado, but I like pushing myself. If there is a 75 mile option, I'd be willing to give that a go as well.
