Try riding in an easier gear and let your legs go round faster. It's the most common mistake most people make. you really shouldn't be pushing down on the pedals that hard unless you are going up a big hill.
Rule of thumb:
Tired legs = too difficult gear
Out of breath = too easy gear
Tired legs and out of breath = get out on your bike more
Well done BTW
Great advice. When I started out I spent the entire time in the two biggest gears. I wondered why anyone bothered with the rest. I also wondered why my knees were killing me. Thankfully, I learned a bit on here about cadence and spinning. I'm just glad my bottom bracket survived those early forays.
