From the roadies point of view that became a tri geek.:
If you like Crit racing, understand the dynamics of a peleton, can hold a line, and want a super fun LT workout with lots of adrenaline... it's a blast.
Do NOT ride with Aero's. One of 2 things will happen: A) We'll ask you to take them off. B) if some of the ego types are there, they will box you out, and leave you scraping for position in the gutter until you pop out the back. Either way, no Bueno!
Years ago, it was designed as an actual race. Then again, that was long before buildings and traffic lights.
It a great way to train peleton tactic and LT threshold burns. The pro's all the way doen to Cat5 JFF riders all go off at the same time. It is a 1 hour ride. Usually there will be a call with about 3 laps to go. The last lap is brutal, if you have not done a bunch sprint, sit back and enjoy the chaos of the bunch sprint. Too dangerous for my blood. If you get popped, it's best to get in at the top hill near the parking area. At least here, it's moving at about 35mph, and most people are recovering after the hill up through the light.
There have been some big names that pop in from time to time. I can remember doing one with Mike Creed back when he was on Discovery. Crazy dude wasn;t wearing a helmet. Tommy D, Mari Holden, Tyler, and a bunch of the local Elites have popped in from time to time.
I have seen some really nasty crashes that have involved broken bones and bikes there as well.
Be careful and have fun. Know when to say when. Be sure to watch your line, and if you are taking one, use the peleton courtesy rule.
Enjoy it. Maybe I'll c ya out there when my base is set.
