To get sub 10 in the 100, you’ll need to ride at a relatively faster pace vs what you did at the Silver Rush.
An estimate of your 100 time is about 1.8x your Silver Rush time (used to be 1.7x based on the old Silver Rush course, but the 2021 course is shorter vs the old course). That would put you just below 12 hrs for the 100.
Using the 1.8x multiplier, you would have had to ride the Silver Rush in about 5:30 to be on track for sub 10 at the 100.
