Would any record set under those conditions be therefore rendered invalid? I understand the reason for the rule and I don’t see how you can compromise on it so I assume the answer is yes. Legal pacers don’t have to finish, but they have to run the entire course from the _start_. In the Nike event, pacers were doing shifts, joining Kipchoge midway through his run and running in formation ahead of him to pace and break the wind. Another data point that the amount of cheating involved here was certainly not understood by “everybody and their uncle”! > [@](#): > > Nike plans to have a six pacers on the track at a time in a triangular formation with the Breaking2 athletes behind them. Those six will come from a pool of 18 pacers, with more reserves if needed, who will cycle in and out three at a time approximately every 5 kilometers. > **[Nike sets out to break 2-hour marathon mark with three elite runners](https://www.usatoday.com/story/sports/olympics/2017/05/05/nike-sets-out-break-2-hour-marathon-mark/101322168/)** > > Nike is doing its best to control variables that could impact performance.
