My 13th half marathon is 8 days away. I’m keen on the idea that a half marathon is 13 miles (let’s not forget the .1!) and that I’ll be running 13 miles for the 13th time. I like the symmetry in that. Since my race last month, I have had a massive breakthrough in my running game. Following nearly 10 months of running injury-free and slowly rebuilding my running base, my VO2 Max has taken off. How did this happen and what does this mean? VO2 max refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise, and is generally considered the best indicator of an athlete's cardiovascular fitness and aerobic endurance. It increases through hard training that produces extra networks of capillaries. The more capillaries you have to distribute red oxygen-carrying blood cells to your muscles and organs, the more oxygen you have to play with. Carrying more oxygen allows your body to work more efficiently, meaning you can run further and faster without bonking.
In the past month, my runs have been consistently 20-30 seconds per mile faster while my heart rates remains the same as they were when I was running 20-30 seconds slower. This enables me to run the same distances I ran a month ago considerably faster without feeling fatigued. For you non-runners, I should clarify that in the running world, running a mile even 2 seconds faster than usual is a big deal. This is a sport where seconds count. I am set up well for a PR, BUT am hesitant to even put that out there. So many factors contribute to a PR on race day. The effort you put into training is a huge chunk of it, but weather, how your body feels race day and unexpected events on the course can thwart PR dreams. A week out, the weather forecast sounds supportive of my PR efforts – not too hot or humid - but what do the weather folk know?☺ What I am projecting is that I could have a PR if conditions work in conjunction with my training. If I PR, fantastic, and if I don’t, I’ll likely clock one of my best races. Stay tuned to see what unfolds at the Summerfest Rock-n-Sole Half Marathon on 6/15/13!
Summerfest has graciously allowed Joe to defer his registration to the 2014 race (many races don’t care what your reason is for backing out, and will not offer a refund or a deferment). Joe offered to be a volunteer at the race, but it seems they don’t need a 1-armed helper, so instead he’ll be a 1-armed cheer-er for me and my friends.
