No, different climbs at different altitudes. They just take me similar amounts of time to complete.
My average cadence for the whole climb was 75. Considering how easy 260 watts is to do on the flat at 85+ RPMs, I strongly suspect gearing is slowing me down.
I have 52/36 and 11-30, but really need something like an 11-34 so I have the option to spin up steep climbs.... especially when I am just crawling.
I will need to change the rear derailleur to use a cassette that big, though. And right now is not really the time to buy bike parts.
That, or just loose the 10 kg I've been trying to lose for several years now. Haha.
I don't know what rear derailleur you are using, but if you want to upsize cheaply, you can buy the cheapest long cage derailleur and switch the cages. I did this when I first started CX 2 years ago.
