For the new racers:
This is a Category C race at Duncan Gray Velodrome in Australia.
This is a "Miss & Out" also known as "Elimination" or "Devil Takes the Hindmost". The basic rule is that it's race where the last person in the pack is eliminated every lap down to 3 riders. With 3 guys left, then it becomes a 2 lap scratch for the finish. So, the fight is to not be last.
This video contains real-time:
- Cadence
- Speed
- HR
- No power
It also shows how close the riders are and how they safely behave.
Pay particular attention to the fact that for 4 minutes, once the rider is up to speed, his cadence didn't drop below 100RPM and peaked out at 130RPM making speeds of 45-55kph (28-35mph). I would estimate his gear to be 50/15 or 47/14.
