It was surprisingly good for the conditions. Maybe 250-300? We certainly didnt have much trouble parking. I dont think many did more than one lap though. Sag/rider ratio was probably 1:1 by the time I was on my third lap. Route was good for what it was. Pavement on that loop is good and it is relatively quiet for most of the route. Was just a 12 mile L-shaped box of right turns. I will see if I can post a strava link later.
