Jeff,
Tuesday is our monthly club meeting, so the ride will probably be shorter than usual, although we will almost certainly ride some of the race course. Also, weather may be a factor for the Tuesday ride.
Thursday is a faster paced ride, the weather looks better, and is more likely to give you a good preview of the race loop. If the weather is good, I plan on riding the beginner race course (might not be enough time for the sport course). Rides meet at 1715 for on-time departure of 1730. If you're not ready at 1730, you'll likely be left behind.
Look on
www.trailspinners.org for ride info and directions.
Also check our yahoo group (link on the main website) in case we do something odd like switch the ride start to a different parking lot to better access the race course.
