Numbered hills with percent grade

Where was the stretch of road with all the hills numbered with the percent grade? I think it was on day 1 just after the “Mile of Silence” but everything tends to blur after a few weeks and your old enough to draw social security. It was a really neat idea. We obviously have hills here in Colorado but I never knew what grade they were. It was nice to know I can still make it up a 10.8% grade.

You’re correct, day 1, near the mile of silence. first time I’ve seen it on RAGBRAI.

At mile 16 you will turn right on Noyes Avenue. You will have ½ mile of flat road. The first hill is only .3 of a mile long but not easy. At 10.8 % this is the steepest of 13 hills on Noyes Avenue that lasts for 4.5 miles.

RIDE TIP: As you ride west on Noyes Avenue, you will be steadily climbing. Do not waste energy trying to power down the hills expecting momentum to carry you over the next. The descents are much shorter than the ascents. Give serious thought to using granny gears.

There was a hill that was 4.5 miles long with 11% grade?

I think d.c.v meant the section of “rolling hills” on Noyes Avenue lasted for 4.5 miles and the steepest grade at any point was 10.8%. Not a single 4.5 mile hill at 11%.

Does anyone know what the percent of climb was on the way out of Ottumwa? That felt like a nasty hill, but it was too dark to see my Garmin. Later I found that my brake was rubbing my front wheel, so maybe the hill wasn’t as steep as I had thought. Thanks!

Lawnchair, Strava says it is 8% average and some short pitches of 11-13%

Thanks George

I suspected that it was a little steeper than the 10% on Noyes road. Thank you for the confirmation.

Some of you might have noticed a sign was put up on Noyes Road that first day. It was something to the effect of “AKA (also known as) Roller Coaster Road”. I loved that stretch of rollers!
