Lol, already CbadRider and beezaur have conflicting points. Beezaur said I could with regular cycling, just not as fast as intervals. And your saying there is no way.

Could anyone link something reputable, maybe a journal article, or well-known cyclist?

@beezaur, the ride has 2 stop signs, and 1 stop light. That's it. Quite a bit of it is low-grade hill, so I'm thinking that should help get me in shape. Way back will definitely be faster though, as there is a rise in elevation along the way there, and a decrease on the way back.


And fair enough, theres not a big different between 25km/h and 30km/h. I was really just wondering if I would improve, however gradual the improvement might be, or if I had to do intervals for example to get my speed up.
