Overview

Maps a set of 5K race times with their pre-calculated pace recommendations. This is useful in testing as well as defining the fastest and slowest supported 5K times. GoldenPaceSet could conceivably be used to pre-compute a large number of recommended paces,

thus reducing runtime CPU overhead.

Constructor Details

#initialize(paces_hash) ⇒ GoldenPaceSet

An example paces_hash is ‘15:00’:‘4:55’

Parameters:

  • paces_hash (Hash) —

    is a hash mapping 5K time symbols to times, represented as strings.
