I can easily bump up to a bit over 20 MPH, but it is hard to maintain it over long distances. So, 15 MPH over 20 miles seems tough enough.
I did a couple of test rides in the last few days... 18.3 MPH for 6 miles
Perhaps I'll work on a summer goal, 20 MPH for 20 miles. Solo. RT. Some may think it is slow... some may think it is fast...
Maybe I just need some new CF and new wheels
It is about 10 miles to the end of my road and back with a few very small hills, and a gradual incline towards the end of the road... so out and back twice would be about 20 miles.
It seems pretty daunting to pick up both the speed and miles
And... I also got close to a double century a month ago... 181 miles. WHEW!!! So, perhaps I'll try to push over that limit too... If I could only think of a reasonable way to add 20 miles to my ride. Maybe finding a more bike friendly route for the last few miles of the ride.
I hope some of the experts weigh in, but I'd expect the training for your 20x20 would be quite different than that for 200x1.
I seem to be a "plodder". So getting speed and distance may be different. However, I think distance even at low speeds does help with overall strength and fitness. And, visa versa, if I can add speed, it will help with strength and fitness, which should help with longer rides. Or maybe just getting more miles down the road before noon.
It looks like I should try some specific training.... other than just getting out and riding.
Spinning??? I do Mash
Pushing how long I can hold 20 or 22 or so average.
I don't have any big hills real close, but I have a couple of small hills that I can play around on. And plenty of hills and mountains if I want to hunt for them.
