I just got the route for my century ride on September the 15-16 and was wondering if anyone could give me an idea on how hard the climbing may be?

Saturday 100 miles: start elevation 742, max elevation 938, Gain 1955

Sunday 65 miles: start elevation 754, max elevation 1027, Gain 1427

I have a 52/42 and 10 speed 12-28

I must admit, im not a good climber and was wondering how hard this may be?

Thanks

That is fairly flat. You will be fine.
If you encounter any obnoxious hills just gear down and slowly spin up the hill.

Here are a few references from my point of view.
Short and steep:

Long and lots of moderate grade climbing:

Flat:

Quite flat, where I ride in Northern indiana I average a total of 900 feet elevation over 35 miles. 12- 28 will handle anything you encounter with ease.

The biggest hill can't be any more than (938-742)= 196 feet, and is probably less.

1955 feet / 100 miles = 20 feet per mile. That's really flat.

Here's a 50 mile route I did, that I consider very flat except for a group of small hills at the start. It's 1900 feet in 50 miles, so it's twice as hilly as your ride. ridewithgps route The middle of the ride from mile 10 to mile 45 has easy 1% grades and crosses a few stream valleys under 50 feet high.

If you have the name of the ride and a nearby city, you can find it on ridewithgps.com if it's been run in previous years.

You are assuming the entirety of the route is at or above the starting point. We can't know that unless we know the min elevation. The biggest hill could be 938 - (742 - 742) = 938 ft, even more if portions of the route are below sea level (highly unlikely, though).

Assuming you don't go too far below sea level the biggest single climb would only be about 1/5 of a mile. Given the length of the course it is probably fairly flat.

Doesn't the race website have a map and elevation guide? Every cycling and running event I've done has provided (a cue sheet and/or online) these.

I would suggest mapping the route on mapmyride.com and they have a feature that you can toggle that gives you a visual of all undulations during the route, and you can compare that to your previous rides to determine difficulty, it is really really helpful

Yup, here it is

Oh, that's mapmyride! They always ignore any elevation gains less than 10 meters, and so their total elevations don't compare to other mapping sites or to GPS recordings.

Here's the same route from 2011 on ridewithgps. The route looks pretty much the same, but the 2011 version repeats a loop at the end, instead of at the beginning.

Ridewithgps reports 4700 feet of elevation gain.

I found the 2012 route: ridewithgps.com/routes/1650629

It's 5000 feet of climbing. The red elevation chart looks very hilly, but it compresses the whole 100 miles.

The few hills that hit 5% to 6% are pretty short, only about 100 feet of elevation. The big hill at the 72 mile mark is mostly under an easy 2% grade, and it's only 150 feet tall. One of the 6% hills is at the 60 mile mark, with 100 feet of elevation gain. You won't need any lower gears than you already have.

The 78 mile mark hill is 3.5 miles long and 200 feet high, but mostly 1% grade or less. That's easy, just shift down a few gears and spin up it. The 91 mile mark hill is similar, 1% for 2 miles. And the 29 mile hill is 2 miles, 150 feet of 1% grades, with a pair of level sections in the middle, and a 40 foot tall 3-4% top part--easy.

The section at the 11 mile mark and again at the 70 mile and 85 mile mark gets repeated, with different exits from the loop! I hope they have good signage or volunteers at those junctions!

Using ridewithgps:
Pull the Map list down at the top right and select Terrain to see the hills. Then zoom in all the way to see contour lines. Each contour line is 40 feet of elevation.

You can also select a hill by dragging a section of the red graph, then you can see the hill's grade and elevation gain from the Metrics tab at the right side of the page.

Ha, you are right, the lowest elevation is 660. ( A 938 foot climb would mean the rest of the ride would be 1000 feet total. That would be interesting.)

Sounds like like Florida-level hills/speedbumps...
