Jake was second and so got $ 60,000, so he had almost $ 500,000 to invest in something, he had already defined how much money he would invest in Cisco shares every year and the rest was for something else.
Jake did it because otherwise he could be tempted to invest all the money he had in stock, that wasn't good for him, even if Jake was sure he would make it he might still need the money for other things.
Just like the house, he would soon have to buy for him and his mother if he was out of money he would have to sell his shares to buy this house which would be a loss for Jake.
As soon as the race was over Jake ate a stamina bar and regained his energy as well as relaxed his muscles a little, soon after the doctors arrived and Jake asked to go to the podium and get the reward before going to the hospital.
As Jake had still run a few hundred meters after suffering the injury and the doctors found nothing serious about Jake's right leg they allowed it.
