Jake was thinking that this running pace was good for his new training, if he could run 50 km a day at that running pace he would definitely feel like he was training for real.
But listening to Coach Davis saying that Jake thought it was true, he didn't know when he could train like that again and it was a good way for him to find out what his limit was after winning so many physical stats.
After the marathon, they would train the 10,000 meters and the 5,000 meters also already thinking about winning the Olympics, so Jake would not have time to further improve his pace of running the marathons.
If Jake could even manage to run in less than 2 hours he would be very happy and feel that he had realized a dream, after all that was one of the main goals for Jake in the future.
And Jake knew that he was really close to achieving this if he slowed down just 2 seconds per km in his running time he would be able to achieve that dream even if it was not official.
