I've been rebuilding my legs since the start of the summer. While playing around with my fit in the spring, I started listening to my legs telling me where they want my saddle to be. For several years I've had my saddle setback at 4.5 cm, but I gradually reduced that to 1.4 cm. My knees are happy, my IT band is happy, no more hot foot and no more saddle sores. I think I was partially too far back, and partially sitting on the wrong part of my Brooks saddle not being supported by my sit bones. The down side is that due to the major change my leg muscles have had to adjust, meaning months of higher than normal HR. My HR is finally getting back down to where it was earlier in the season. But its difficult to get a good feel for my conditioning dealing with 30-50 km/h winds nearly every day this time of year.
