I want to do the Mt. Tam Double, but there's a strict time limit, and I'm concerned because I'm slow as something that's really slow.
You can't start earlier than 5 am, and must finish by 10:30.That's 17.5 hours.
I've done the Knoxville Double in 19 hours, and 18:22
I did Devil Mountain in 20.
Not to swell
But I did manage Solvang in 14:30, and Davis at 15:30 and 16
So, wise experienced cyclists, if you've dome Knoxville, how does it compare to these rides?
Would you bet I can hit 17.5? I've never DNFed a double. I'd hate to pay, ride a long way,and be taken off course
