Hey team, I’m looking to get some data. Power required to do 32kph (20mph) Power required to do 40kph (25mph) I’m only interested in road bike data. Please include as much detail as possible. It needs to be a flat road, no wind if possible. Definitely not tailwind numbers. Include detail on qua…

Tell me you live in Florida without telling me you live in Florida…

This was by yourself and not in a group? Was this on a TT bike? Not saying this isn’t possible but it seems highly unusual. Then again I’ve never lived somewhere flat. The numbers you posted are consistent with TT bike numbers.

100 miles with 89 feet of elevation gain with a time of exactly 4 hours? Did you do this on the trainer with simulated distance?

That looks low to me also…but I’m also nearly 20kg heavier. They dont look…super duper low to me. I’m just going off of memory and not hard data, but I’m pretty sure I’m around 210 watts at 20mph on the hoods. 6’, 185lbs, flat ground, cross bike with 55mm deep wheels.

[image] Abe_Froman: pretty sure I’m around 210 watts at 20mph on the hoods. 6’, 185lbs, flat ground, cross bike with 55mm deep wheels. About the same watts at 20mph, I’m a little bigger and Tarmac SL7 with Rapide CLX2 wheels around that same depth.

Yea that makes sense. Tad bigger…but bike probably a shade faster on the road. I’m honestly only really confident about my numbers because when I’m in shape…I shoot for zone 2 rides around that wattage and generally cruise around 20mph when it’s flat and calm. I think my 25mph numbers are substanti…

By tad bigger I mean 1” taller and 20lbs heavier. And I do a lot of endurance rides on pancake flat ground. In the summer when it’s warmer, on the rare no wind day it’s something like 19.5mph at 200W.

Obviously this depends a TON on terrain, road surface, and conditions- even without hills, good road surface make a huge difference over slower road surafaces, and in flat coastal areas, wind can really slow you down if it’s swirling or a headwind vs a crosswind. With those caveats, I do a fair amou…

On my TT bike it takes about 225w to do a sub four hour century. I’ve gone 27mph for 100 miles with around 270w on my TT bike. I live in south Florida. It’s flat albeit it’s still not easy holding this power without stopping and maintaining a proper position. I encourage anyone to try it and if you…

It was competed outdoors. It’s exactly 4 hours and one hundred miles because I held 25mph. Do the maths. :slight_smile:

I wish I had some decent climbs in our area. Central and north Florida are hilly and I really enjoy riding in that area. The route I mainly do for these type of rides is flat and has no stops and when the wind is low it’s a nice.
