AR would allow each athlete their own personal pacing grid, or ghost racer, or ideal line. You can run that on a watch or bike computer (or heads-up display), but AR would be that much more intuitive.

It doesn't apply to this one-person demonstration event, but it would sell like crazy to the gear nuts.

phkahler thinks if the record attempt is invalid because of the team of pace runners, why not use a simulated pace runner to gain the benefit without breaking the rule?

Of course, if the speed benefit of pacing is down to psychology and camaraderie rather than purely information, a simulated pacer might not offer the same benefit.

There were 3 reasons why the record is invalid: swapping pacers, drinks handed directly to him by support team (on bicycles), not an 'open event'.
