 Northeast Hillclimbs Calculator Page Disclaimer These Java Script calculators can aid hillclimb cyclists in making correct gearing choices and in estimating climbing time. Most will obtain fairly accurate estimates, but a few could be way off. Remember, garbage in, garbage out. An estimator is only as good as the source data and assumptions it is based on. The models used here are simplistic, using a rolling/wind loss paramter that is average over several different climbs and riders. Use these calculators as scratch pads only, something to get you in the ballpark. Then go out and test your fitness, gearing, or whatever you are estimating on a climb. These calculators are no substitute for the real thing. Many thanks to Mike Bergstrom who provided the initial climb translator script to get me started with Java Script.

 Mt Washington Time From Other Climbs Select a climb, estimation method, and the time from which to estimate Mt Washington time, then click "Calculate". Estimation is based on actual race results over the last few years. The linear regression method may be more accurate for some comparisons. Based on sample data set, you have a 68% chance of falling within the standard deviation error shown below.

 Cadence Estimator Select a climb, an estimated time for the climb, your nearest tire size from the list, and front chainring size. You can select one, two, or three cassette cog sizes with the percent time you think you spend in each cog. Only caveat is that your percents must sum to 100%. Not all climbs are available with this calculator. Only steep, mostly monotonic climbs are listed. Climbs that have large downhills, or extended flat sections will make estimating average cadence unreliable.
