If you ride the circumference trail CW( just the west side thru the saddle) it would be about 3 mi and very tech in many places and no sand.
big0mike's tech standards are very high... from what I can gather

So maybe Deem's is just plain too easy...
If Deems is too easy, I really suck.
No, Deems Hills is not easy by any means. The list of people that are slower than me is definitely a very small list. Back when I rode it a few times I could tackle the west mountain loop without stopping. Doubt I could do it now 'cause this summer has destroyed me for some reason. I was hoping to make it to 50 before I started falling apart...
But, Deem has never had anything resemble technical moves. And, by technical, I mean Cheesegrater, Hairball, or National technical. I'll have to make a visit out there just to see if those trails are as beat up as as most of PMP.
My favorite loop is a figure 8. West side CW around to saddle, down then E to the east side and up around and back to the saddle. Then back to the west lot. The climb from the bottom SW corner of the trail up the east side was always brutal.
