Training for the Winter Olympics is hard. Just ask Shiva Keshavan. The 32-year-old luger is set to represent India at the Winter Olympics for the fifth time next month in Sochi. Because there is no luge track to train on in India, Keshavan has had to improvise. “To practice, what we do is modify the sleds, we put roller wheels on them instead of blades and go down the only place we can — which is the mountain highway,” Keshavan explains to Time.com.
