Today's ride was just a few laps around Mastline Dr. At one high spot the hill drops about 100ft over about 1/4 mile while turning left. I hit it hard and maxed out at 32mph! That's 5 mph faster than my best on my standard hybrid bike. If it were a straighter hill without the blind left turn, I think 35mph is achievable. The 32mph felt plenty fast enough for the conditions:) I'll need to head over to Harry Truman for higher speeds with it's hills more like 150ft and is straight!
