20 miles saturday and Sunday, normaly do 15ish.
I’m not really one to winge but have a bit of aching going on below the knee caps.
Before I google diagnose 🙂 Any ideas on why and what I need to do to prevent this?
Cheers

Patellar tendonitis.
Rest, Ice, Stretch, anti-inflammatory drugs if needed, make sure your saddle height is correct, make sure your cleats are in the right place if using spd style pedals, when it gets better, try going longer but more gently to get used to the distance.

Oh, and if you have to kneel down in front of anyone, use a pillow for your knees.

You need shorter wellies. 🙂

Raise your saddle a touch.

Get a fixie and learn to spin rather than mash?

Google says its because I’ve gone from a full sus to hardtail, and I might want to put my seat further back.
Sound about right?

Google told me it was because I had gone from gears to a singlespeed.

The physio told me I needed to stretch my quads.

Putting your saddle up a bit means you flex your knees a bit less. Shorter cranks do the same thing but is more expensive. Personally I used to get knee problems but they went away by doing that and switching to SS. But everyone’s different and I could be talking rubbish (this is STW after all). YMMV.
