Louise Ferguson's run of the 2019 Megavalanche Female Race (Descent World video: https://www.youtube.com/watch?v=baDq9Ot7iFA) matched with a Ride with GPS course .gpx modified with GPX Track Editor to add timestamps approx. matching .gpx file length to video file length.

Amazing rider.

GPS timestamps were generated by dividing the course into 11 segments based on prominent landmarks or terrain, calculating each segment's average speed, using this to generate appropriate timestamps to render segment length approx. equal to respective video segment length, then merging all 11 segments back into a single course. As the rider's speed obviously varies throughout, note that map position, while generally close, will not sync as accurately as expected had a .gpx file been captured real time from this specific run.

As this is primarily an extended off-road mountain descent you may wish to increase Kinomap's difficulty setting (c. 140% worked for me), however if you do increase difficulty pay attention to the occasional red slopes in Kinomap's grade profile and downshift or decrease difficulty before really needed. Hitting a red slope at high gear & difficulty settings can rapidly make smoothly shifting to lower gears extremely difficult & may become too hard to continue pedalling.
