Please update to the current version if you are getting a CIQ crash (!) showing in app. 
This is feature extended version of my prior datafield. https://apps.garmin.com/en-US/apps/6257a0bf-058c-4d8e-a9c7-a951852132e0 
As with that one this is primarily written for my own needs but feel it might useful for others hence the public release.  Because of memory limits on older devices I have to release it as a new datafield and it is only avaialble for newer watches with a memory limit greater than 28K. 
The primary function is to give you a real time prediction of your estimated finish time based on a configurable window backwards in time and warn you if you're going faster or slower than your target pacing for your target finish time.  The new features include prediction weighting, tracking checkpoint distances and mileage correction.   
Since I wrote this primarily for use in ultra marathons, I've written it to be as power friendly as I can to keep the battery hit to the minimum possible, 90%+ of the calculations/code only run on the delayed update tick. Features that aren't configured like checkpoints or pace warnings don't get calculated to save cpu cycles (and power).
It will predict shorter races, I've used it for 5K's. 
While I've tested it on the watches that in theory should be able to run it using the Garmin simulator, I've only real world tested this version on a Fenix 6X.
Features:
You got this: An runner set inspirational short phrase that will flash at you on the datafield while it's paused pre start and the datafield is on the screen. 
Finish Time: Predicts your current projected finish time for the target distance based on a configurable look back time window and update cycle.  
Weighting: You can set a weighted predictive average from 50% to 100% of the lookback window. This helps average out highs and lows if you have the weighting less than 100%. 
Pace Warnings: If you're too far ahead of or behind your overall target finish time (or next checkpoint) it'll display how far ahead or behind you are.  You can set how big a percentage off pace it should trigger on and change the color of the watch face and text.  Defaults to red face for 'too hot' and blue for 'too cold'.
Better Elapsed Time:  Elapsed or Remaining (predicted) time in hours and minutes (who gives a deuce about seconds in a hundred?) to work around Garmin's ridiculously tiny hours font when it goes double digits.
Race Checkpionts: Add up to 9 checkpoints over the course of the race with a distance, time and optional name.   The display will predict how far ahead or behind you are to the next checkpoint time and optionally flip between the elapsed time and checkpoint time in one of the 3 fields.
Mileage Correction:  Set up to 2 'mileage correction' checkpoints and correct the prediction using the pause button to trigger them.   For example say there's an aid station at mile 52.  So you can add a correction checkpoint of 52 miles.  When you get to that aid station you see your watch has measured 49 miles.  Pause and unpause the activity and now the datafield will predict on the corrected mileage.  You can set a second correction checkpoint further down the road as well to re-correct it.   Pause a 3rd (or more) time to disable corrections. 
Non-Moving Tracking: It can track non-moving time in real time and display it on screen if it exceeds x% of your target time or always.  You can also turn on a real time non-moving timer that will start displaying each time you're stopped for 60+ seconds. Non-Moving time is based on cadence, not GPS data to avoid GPS 'scatter distance' during stops. Non-Moving time is displayed rounded down to the nearest minute and only displays when there is  1+ minutes of it. 
Color Configurable: You can of course change the color of the screen and text and have different colors for being hot, cold and on pace.
