* This Calculator will also attempt to compensate for races run in hot conditions. This is based on the research documented at [[Impact of Heat on Marathon Performance]] and is an estimate only. If you enter your weight, the calculator will predict your race performances at different body weights, assuming the weight change is due to body fat only.
* This calculator no longer generates VDOT paces nor will it output the [[Long Run|long runs]] for the Jack Daniels marathon plans. Jack Daniels requested the removal of this functionality.
* If you provide your body weight, the calculator will display running power for each pace. It uses the simple "1 watt per Kg per meter" approximation, so it may not align with [[Stryd]] perfectly.
