I started riding a fixed gear almost 2 years ago. I have never ridden on the track - only the street (brakes front and rear).

For me, it was like a 'reset button'.
Felt like I had to lean how to ride all over again. Hills both up and down were a new challenge and long rides like centuries and beyond had this little bit of uncertainty to them about whether I would be able to make it... just like it was when riding geared bikes long ago!
