Position on saddle

[Andywinds]

I only tend to move forward when climbing, I've taken this from MTB techniques over the last couple of years. And also on some sprints. There is no way that I would want to do this for more than 10 minutes. I have just moved my saddle back a little, I've also used that technique where you dangle a line from the base of the kneecap so it intersects the pedal axle.

Notice what's happening, the front rider is in close to maximum effort - as a cropped picture it's hard to tell but it could be the early part of a break when putting some time into the peloton is priority, before settling into a more sustainable pace. Then everyone sits back a little. You simply can't ride (or race) 200+ km sitting on the nose of the saddle, unless you enjoy a tender undercarriage (or worse). The pelvic bones need to be supported to avoid excessive compression of soft tissue. Females generally have a wider pelvis, hence female specific saddles are a bit wider at the contact point for pelvic bones. So, use manageable gears, sit back and enjoy more.

That's a very valid fore and back way of setting position - just be sure you are on level floor and the line has a nice little weight to keep it perfectly straight.
It served me well for a long time, as did the 0.883 sum for saddle height. After which all that's needed is setting up shoe plates (yes I'm that old, clips and straps), and away you go.
Hoping for some better weather tomorrow, grey and chilly - makes Andalusia very attractive for winter base miles in November. You get used to nice weather, then in February some rotten so and so's run all these wet, cold, pave littered races in Belgium!
