Coincidentally, the Disciples left with Bucky Barnes were also subjected to the grueling marathon... however, they had no choice but to go at it without using their superpowers.
For some, it was incredibly easy, but for those who were only strong in the superpower sense, this was one of the most challenging tests they could go through. There was also a time limit of two hours, which was already a lenient amount of time considering that they were all peak human Disciples.
A handful of Disciples like Arghus (peerless disciple) and Bruce (main member of Satoshi's party during the three-day survival test) resolved to break through their limits and complete the marathon in under thirty minutes. As for the majority, they went with an even pace of 21 kilometers per hour, barely making it in time to finish the race in under 2 hours.
