It’s a big week for racing on TV as three major touring series begin their year while another stages the second round of its season. So TV will be crammed with action this weekend. Last Sunday was qualifying for the Great American Race, the 57th running of the Daytona 500 but only the front row was set. On Thursday the rest of the 43 grid spots will be filled with the two Budweiser Dual 150 races.   Those on the inside row race in one event while the rest on the outside row from qualifying also get their chance.
