A local club was doing TTs on one of my favorite courses. It's about 9 miles with 4 steep climbs and ends at the top of the 4th climb (technically 5th given the small drop and climb again). I asked what times people were posting and they said around 25 minutes was the high end with plenty of people in the 40-45 minute range and even some around 50 mins. My time over the same course was just under 33 mins.
Just to give you something to compare to not to brag about my awesome speed
