The point was the hill is only 133 feet high, at 11% it's about 1000ft long, less than 1/4 mile. The duration of the climb is very important as well as the grade and in the case of this racetrack hill there's just no duration. It's over in less than a minute for a fit cyclist. You would hit the bottom of the hill at > 20mph and your momentum is going to help you get partway up the hill before they hit the point they even have to climb at a steady speed. It's not even long enough for "climber" type cyclists to be able to start dropping heavier sprinter type cyclists because it's a quick little effort and you're over the top. Even if you're in a race and had to do 10 laps (a short beginner level distance) you would still only climb 1330 feet across a 30 mile race, which would generally be considered a fairly flat race. The Tour De France has a classification system for climbs.. this one would be so short it would not necessarily even get a classification since it's not even 0.5km. A really scary climb would be > 10% for 10km or more. I had mentioned the Mt. Washington Hill climb in NH. That is 7mi/11km at a 13% average grade with essentially no letup the entire climb and some sections exceeding 20%. An excellent time is anything under an hour and twenty minutes and if you can break 1 hour you're putting in a world class performance. A winning time up that mountain would considerably longer than a 10 lap race of COTA, average speed at COTA for an elite group would be around 30mph for 10 laps of COTA in all likelihood. The hill at this race track is not even going to register to most serious cyclists.
