The 2013 Boston Bruins training camp officially begins Wednesday. Over the past couple of camps, Brad Marchand has been at the top of the team’s fitness tests. No one doubts Marchand will be in terrific shape once again after a summer of demanding training in Halifax NS. Marchand blows away the field of fellow pros in a competition including the hammer and the sled. Here’s a video of the Bruins young star who also earned an invite to the Olympic team camp for the 2014 Winter Games in Russia.
