I currently ride around 14mph for a 20 mile ride on road, and I seem to be stuck at this pace for the last month.
My friends/strava cyclists regularly churn out 18,19+mph on their roadbikes, with seeming much less effort.


Any tips on how can I become faster?

Some information about me -
I'm 6'4" 200 lbs in decent shape. My bike is the 2021 Specialized Diverge Carbon Sport (gravel bike).
I started biking 4-5 months ago. I am very slow on climbs!
