OK, Silver and I rode a metric this weekend in Evansville. It was 65 miles with (to our total surprise...because SW Indiana is fairly flat) 4,000 feet of climbing (about 61 ft/mile). Click "Dashboard" on this Garmin Link.
The question comes when compared to the seemingly Hilly-er Day 2 of the Hilly Hundred last year on this Garmin Link. This ride had 3,700 feet of climbing in 50 miles (about 74 feet/mile).
Garmin "Elevation" indicates that the Hilly Hundred had an average ascent of 3.6% with a max of 18.7% while the Pumpkin Metric was 2.4% with a max of 13%.
Granted, a 15 mile distance is a huge one in measuring climbing. But it begs the question: How do you gauge hilliness? Feet Climbed? Average Ascent? Max Grade? Ascent/mile? ...or whether you simply want to yak at the top?;)
