Hey Slim,

Which one are you looking to do? 30, 70, or 100? They have slightly different profiles.

Generally speaking it's pretty dang flat. There are no big climbs (except maybe the start of the 30). You may find yourself just grinding away for miles thinking you must be totally gassed only to finally figured out you've been on a false flat for the last 7 miles.

Outside of a few miles of really loose sandy stuff on the 70 and 100 course you will find the surface very ridable. I haven't been out there this year to see how things are right now. It's looking like rain this week which would actually probably firm up the sand some.

They've got a pretty good course description up if you look on the website or linked in the latest post on the Cyclova website.

If you've got specific course questions fire away. I've ridden all the courses multiple times.

Ben

That's my Strava file from the 100 last year. 1500 feet of climbing, but nothing of substance all in one shot.

Thanks Ben,

I was thinking of the 70 miler. Living in Duluth, I haven't been on the bike much recently, since the fatbike trails melted out early. Gravel's great now but just starting to ride again. So 70 miles seems like a good prep distance for the Almanzo 100.

Yeah, 1700' over 70 miles would seem to indicate a lot of nearly flat riding. Looking at the elevation profile it is indeed a long slog up a false flat and then bomb down to the finish. I would rather go the other way! Get the climb out of the way in the beginning, then have a bit of a boost all the way along. ;-)

Are there any noticeably  climbs on there (or ones that feel steep because they are soft sand)? The 70 mile elevation profile can easily hide a 20% hill of a few hundred yards.  If so, how much elevation and or how steep of a grade?

Slim,

Here is a link to a 70 mile Strava file from last year.

https://www.strava.com/activities/547434383

About the same amount of total climbing, but there are some actual hills on the 70, whereas the 100 is generally much more gradual.  The hills are pretty much all between 35 and 50.  As I recall a lot of them are actually paved, but I could be misremembering.  Nothing huge, but you'll definitely know you are going up a hill.  Unless you are running some crazy high geared single speed there is nothing you would be in any danger of not being able to ride up.

A very brief course description.

0-17 - 95% pavement.  Gorgeous along the St. Croix river.
17-24 - SAND.  Lots and lots of sand.  Don't ride your 25mm tires.  40mm and still swerve all over and potentially hike a bike a few stretches.  They don't call them the sand barrens for nothing.
24-49 - The section I've ridden the least for sure.  I think a fair bit of it is paved.  A bit rolly.
49 - Stop at Cafe Wren for some goodies.  Love that place.
49-end - Mostly flat rolling along the Gandy Dancer.  It was pretty firm yesterday.  A few ruts from a few vehicles and actually quite a bit from bikes to just keep an eye on.  Once past Centuria its pretty much all down hill back to SCF.

It is a beautiful and challenging course despite the lack of elevation gain.

Hey Slim.  Did you come down and enjoy the "beautiful" weather and course this weekend?

The hundred was pretty awesome.  I rode with the lead pack until we got to the Gandy at mile 63.  The Gandy was about as bad as I've ever seen it between Bass Lake Rd and Frederic.  10 mph was a Herculean effort in the softest surface false flat I've ever seen.  Thankfully it improved significantly from Frederic back to SCF.

Nope, ended up enjoying the first mob ride of the year with a few families in Cuyuna. Great weather there, shorts and T shirts, 66 F and sunny. Trails were damp hero dirt.

Sounds like an epic ride! post up some pics!

I'm working on a report with pictures.

We went to Cuyuna Sunday for a "recovery" ride.

Finally got around to finishing my ride report.  A ton of fun was had.  Type 2 fun to be sure.
