Assume that a given biker is adequately prepared for a century ride, but is not a 'serious competitor'. For the number oriented reader assume a base of 150 to 200 miles per week for the previous couple of months (including some long rides). IOW, reasonably prepared but not competitively prepared.

If this rider is riding a Century ride on rolling terrain (assume less than 5K total climbing), what kind of average HR would be a reasonable expectation (as a percentage of LTHR or average HR on a best effort 30 min TT). Again the rider is trying to attain a best possible total time given the circumstances.

Just curious - thanks.
