I've also ridden once with a loaded back-pack on my other bike (8.5kg Trek). I wasn't really that much slower with that. And that was years back when I was hopelessly slow.
Now I'm much quicker than that, and I can definitely accelerate much faster. When I look at my averages, the Garmin does auto-stop at traffic lights and below 8km/h, but I do generally roll up to traffic lights so that also kills the average speed a lot.
Depending on where my work moves to in the coming year, I might start doing commute rides, all the potential locations look decent for that.
I do believe we are agreeing here;
A motorway shoulder has a good surface and the vortex of the traffic to suck you along. Hi 30s or even 40s are quite maintainable. This is my point.
You can't compare this to riding in most other enviroments.
Here in perth we have a PSP that runs very close to the freeway, going one way you average 25, going with the traffic 35+, what are we comparing?
I could choose to use my average going with the traffic and quote a good average, but to be realistic you should add the average going both ways and dividing by two. This is realistic.
To commute some where doesn't always give idea routes, you may have a head wind one day and a tail wind another. These make a massive difference to your speed.
Im over fifty, so im sure some very fit young guys can whip my ass. There are so many variables to consider. All im asking here is if you are comparing averages there has to be some kind of difined criteria, otherwise it means mute.
Taking all diferent routes and conditions into consideration, 25km I believe is a good pace.
