What's the steepest hill you've climbed on a bike? (Page 2)

 Is it called ilchester

Wow,

I thought 11% for 1/4th of a mile near my house was difficult.  31% for any distance seems like pure insanity to me.

Smoky Valley in Austin.  It is between 26-29% grade.  It is on the morning loop of Tour das Hugel which takes place every November.  Think of it as an all you can eat hill climbing buffet!

Sugarloaf Mountain near Clermont FL, highest point in Florida, which isn't saying much ;)  Anyone familiar with the Great Floridian IM or Florida Challenge HIM route knows the fun.

Using BT route mapping, it has a mid 1/3rd mile section with 162 ft climb for an average 9.3% grade with a short durations at 13%. Total climb from bottom to top is 0.61 miles and showed a 7% avg grade.  Got up using a 39/25.

3 miles before Sugarloaf is the Wall, nice little warm up climb for 1/3 mi with an average 6% grade and a short 12% section.  A few miles after SL is nice hilly stretch called Buckhill or the sisters.

I forgot to answer the original question in my post re: the Manayunk Wall - steepest hill I've ridden is Constitution Hill in Swansea, UK.

Not sure of the grade but it's cobblestone and used to be a "highlight" of the Milk Race in the UK. I did it sometime in my college years, not sure I could do it now.

I am in Arizona "visiting".

Did my first half century mid feb going from Ft. Huachuca to Parker Canyon Lake...

Here's the profile:

The low point (right before the 10 mile point) is about 4800 feet. I climbed into the mountains for a little over 8 miles. that was a tough, tough climb. I have no idea what the grade (steepness) of that climb is.

 It is calculated with rise over run .. rise is 5715-4800 = 915 run is 8.1 miles in ft is 42768

Boltinghouse road NE of Bloomington IN (as mentioned in Bicycling mag).  Short 1/4mi but 23% with sketchy pavement & no lead-in.  The Hoosier Mountain Bike Club holds an annual road bike century ride in August which includes this brute along with most every other 10+% climb they can find between south Indy & Bloomington. 

The annual Hilly  Hundred ride out of Ellettsville IN boasts the near-as-steep Mt Tabor (also short 1/4mi @21%) as its bragging hill.  The facts that this ride attracts bikers of all abilities (or inabilities) crashing around you, Mt Tabor comes after multiple other 10-15% hills,  and the local car traffic can be somewhat hostile all add to the survival challenge

I'm not a native Hoosier but I learned real quick that parts of southern IN are NOT flat!!!

I did the NorCal triple this wknd. Did it all on my Cervelo p2c, noncompact crank, 53-39/12-25 gearing.

I tried to follow this route, the "ring of fire" , with added hills to make it harder. (Added Old Lahonda and some other climbs on top.)

I didn't quite read the instructions right, and didn't realize that the route they outline has you going DOWN the 19.5% incline on Joaquin. (It's also 0.4 miles long, following another 2 mile climb of 7-11%)

I ended up climbing UP that nasty stretch of 11-17-19.5% on my TT bike - it was really, really hard, but I somehow made it all the way up without unclipping once. I didn't realize how steep that section was until I was home. After doing that, the inclines of 11% felt like easy flat road - it was pretty weird!

Sometimes it's just better not to know!

I stand corrected, Sugarloaf is the highest point in peninsular Florida!
