New version based of data field "Fields of Gold" by kurtie_bcn. The original version supports only Forerunner 230/235.
By permission of the author I added support for some new models with round display (240x240):
Forerunner® 245, Forerunner® 245 Music, Forerunner® 645, Forerunner® 645 Music, Forerunner® 935, Forerunner® 945, MARQ™ Adventurer, MARQ™ Athlete, MARQ™ Aviator, MARQ™ Captain, MARQ™ Commander, MARQ™ Driver, MARQ™ Expedition, fēnix® 5, fēnix® 5 Plus, fēnix® 5X, fēnix® 5X Plus, fēnix® 6S, fēnix® 6S Pro, vívoactive® 3, vívoactive® 3 Mercedes-Benz® Collection, vívoactive® 3 Music

Functionality is nearly unchanged, I only added the actual time at bottom. 

Here the description of the original data field:

Fields of gold is composed of 6 fields on screen:

- First field is a graph of heart rate graph or altitude. Graph scale is configurable.

- Second field is a virtual runner) with configurable pace, graphical representation of position, and distance in meters.

- Third field is a timer

- Fourth field is distance

- Fifth and sixth fields are configurable and can be one of: Average pace, current pace, cadence, stride length, calories, training effect or energy consumption

It also spots on the right a bar with the available battery. The bar is green if there are more than 60% of battery, yellow if between 40% and 60%, orange between 20% and 40%, and red below 20%.

Some words about current pace (it also applies to stride length because its calculation is based also on current pace): there are some issues with it. The current pace calculated by the Garmin watch is way too smoothed for my taste so I tried to do a more 'raw' pace calculation based on the average of the last 10 seconds (the amount of time is configurable but cannot be very high because of memory constraints), but while in the simulator it works well, used with real GPS data is not working (too many spikes). It is included because some people may prefer a more responsive pace (even with ocasional spikes) than the built-in pace by Garmin, much more stable, but quite unresponsive.

GPS is a great positioning system, but it is not very good for doing speed calculations at low velocities dued to precission issues.
