Why Am I So Slow on a Bike?

I’m going on vacation to Venice with my boo’s parents and they LOVE to ride bicycles everywhere. They own a place there and have their own bikes and rent us some so we can bike to every restaurant, bar, or event.

At first I was always excited about it but I have realized something over the several vacations together…

I AM SLOW AS F*** compared to them.

Biking makes me miserable because I can’t go the pace that is comfortable for me. They are freaks, especially his mom, about how fast they peddle and get going. My knees and body hurt by the time we get somewhere and I am sweaty and disgusting. I am literally out of breath the entire ride and they show ZERO distress and are totally enjoying the scenery.

What is crazy is I am really fit. I work out 5 times a week, yoga or cardio, I eat really healthy, I’m petite. I’m not out of shape at all.

Why does riding a bike seem so much more difficult for me than others? And why does it get me out of breath so badly?

One trip I was left in the dust and I complained a lot about being over exerted and they said my bike was the problem so I switched with his mom and guess what??? She still left me in the dust and I felt exactly the same.

I even bought a bike at home and I try to train myself and get an endurance for it but I still just can’t keep up.

Is there something wrong with me?
