Here are a couple of screenshots from my attempt to visualize the progress of all three riders in the One Year Time Trial
(click to enlarge).
Godwin's 1939 progress shown as the grey line, Steve in red, IronOx in green, and when he appears, Tarzan will be in blue.
This is basically a time against cumulative distance graph, but standardised with respect to the distance covered by a ghost Tommy Goodwin continuously riding at his average pace of 205 miles per day. So a rider who managed 205 miles per day would progress horizontally - any faster than that and they would move upwards, slower and they start sloping down. A stationary rider would slope down parallel to the steeply sloping lines seen towards the right (you can spot Tommy's only rest day on October 28th).
The vertical axis therefore shows how far ahead or behind Tommy's ghost a rider is at any point in time. As you can see, Tommy himself was below his 205 miles per day speed between January and May, after which he started to increase his daily pace until November. By standardising distances in this way, it should be possible to compare all four riders' progress even though they started at different times.
The brownish zones to the right represent the previous world records between 1911 and 1939, so if all goes to plan, we should see those being hit from around June onwards.
After the first week, you may just be able to make out that Steve (in red) is above Tommy's actual Jan 1-7 pace, but below that year-long average. IronOx, with only short rides so far, is already 700 miles behind Tommy's ghost. Below is an enlarged section showing week 1.
This shows food and sleep stops (downward sloping lines). Should be interesting to compare once Tarzan starts and we get to see the tortoise and hare together.
I am still sorting out a few minor bugs in the interactive version of the software (damn you IOS), which will allow you zoom and pan around the charts, but it should appear here soon. The software is being fed by the GPS data from Strava, so should get updated once per day.
Any comments on the design / suggestions for improvements are welcome.
