Optional Loop 2: (From Altamont)
R- Black Mountain turnaround at stop sign (Natoma), climb Black Mountain, R- Altamont

There is no regroup on Altamont. If you are behind the lead group, you can turnaround early and catch up to the group. Do a safe turnaround in an area clear of other riders, don't just jump in front of other riders. Don't underestimate the time it will take for you to turnaround and get back up to speed moving in the other direction. Leave plenty of clear space between you and other riders.

Safety:

1. Obey all traffic laws.
2. Whenever you use aerobars, you are subject to USAT draft rules. No one within 3 bike lengths in front or behind you.
3. No passing on the Altamont descent, there's a dangerous sharp turn in the middle of the descent. Control your speed until you get passed the S-turn.
