A "virtual" Race Pacer that allows you to pace a running race or a training target distance.
**NEW BIG font version of Race Pacer now available: https://apps.garmin.com/en-GB/apps/ae0c55f7-4abe-4f8f-a0d8-fabc7d895120  
The virtual "Pacer" also has two key features:
   1) Adjusts the required pace for changes in gradient (Gradient Adjusted Pacer). So it will pace you slower up a big hill, and faster down...!
   2) A "race split" can be configured, for example if you want to run a -ve split running 15 seconds/mile quicker at the finish compared to your target average. The "race split" is a "linear" progression so in this example you would run +15 secs/mile at the start, target average in the middle and -15 secs/mile at the finish, etc..

Usage:
1) Using Garmin Connect Mobile or Garmin Express set the Race Pacer App Settings for your desired race distance, target time, start elevation ("-" for current value), elevation change,   "race split" and optionally GAP adjustments.
Example: I want to run 10k(6.21miles) in 48min:30secs with a -ve split of -15sec/mile at finish compared to middle average. My start altitude is known to be 50 feet, and finish is 100 feet higher than start.
In GCM or GE enter:
    Distance = 6.21
    Target time = 48.5
    Start elevation = 50   (use "-" if you don't know and use GPS current elevation, but can be less accurate)
    Start-Finish elevation change = 100
    Race split = -15
    (the rest defaults)
For device set to statute units are miles/feet, for metric device units are km/metres.
2) Start Activity... field displays:
     A: "current altitude" D: "Start-Finish elevation difference"
or S: "specified start altitude" D: "Start-Finish elevation difference"
  "race distance" in "target minutes"
  P: "pacer start pace"-"pacer finish pace"
when "GPS Ready", check your elevation is about right (if not specified) before you hit "Start"...
