Jake was able to do this with the help of the system that showed him the distance covered in the run, the pace per minute he ran and the race time too, but after a few years Jake's body also adapted to the system and he didn't make more mistakes than he did when he started running.
Now Jake just used the system to make sure his running pace wasn't wrong because his body knew how to change the pace for a few seconds faster or slower, this was also a talent that Jake had that was greatly enhanced thanks to the system.
Jake ran the first 2 km and realized that he did not try as hard as he thought in this training, it was almost the same as he felt when he ran the second time the day before, this meant that Jake would achieve more would also suffer a little.
