Overview:

The difficulty of a bike ride is typically expressed by two numbers: the total distance traveled, and the cumulative elevation gain. Over the years there have been various ideas for combining these two numbers into a single estimate of how difficult the ride is. For example, is cycling 20 miles on a level road easier or more difficult than climbing 2000 feet? Up until now, it has been difficult to find an answer to questions such as this. BikeEnergy can provide these answers. The companion app BikePower estimates your instantaneous power output while riding. This app, BikeEnergy, estimates the total energy you expend during the entire ride. BikeEnergy estimates the total amount of energy (Calories or kJoules) required to ride a bike route characterized by total distance and cumulative and net elevation gains (along with a few other parameters that personalize the results for your specific weight, type of bicycle, and riding speed). Energy is an excellent measure of difficulty. A ride that burns up 2000 Calories of energy is in a very real sense more difficult than one that consumes only 1000 Calories. Not only will you feel more tired after a 2000 Calorie ride than after one that burns 1000 Calories, but you will also have to eat more food to replenish your energy stores for your next ride.
