func Bisect ¶

func Bisect(fn func(float64, float64) float64, a float64, b float64, tol float64,
	maxIter int, raceLengthMeters float64) (c float64, err error)

Find the root of the function (in this case, CalcVO2max) by bisecting https://en.wikipedia.org/wiki/Bisection_method The function argument (fn) signature is specific to CalcVO2max.

func CalcVO2max ¶

func CalcVO2max(v, t float64) float64

Calculate V02max using the Daniel's and Gilbert formula. The velocity is expressed in meters per minute. The time is expressed in minutes.

func Daniels ¶

func Daniels(runLengthMeters float64, elapsedTime float64,
	raceLengthMeters float64) (tOut float64, VO2max float64, err error)

Calculate a predicted race time using the Daniel's Gilbert VO2max criteria.

func PredictRaces ¶

func PredictRaces(runLengthMeters float64, elapsedTime float64) (PredictedTimes map[string]float64, VDOT float64, err error)

Predicted race times using the Daniel's Gilbert VO2max criteria.

func TrainingPaces ¶

func TrainingPaces(VO2max float64) (easyPace, maraPace, thresholdPace, intervalPace, repPace float64)
