Sunday May 30th 2010, I participated in the half marathon in Ottawa. It was my 3rd attempt at this race. The weather was perfect, 17c at 9AM and 19c at 11AM. No sun and a bit of rain to keep us cool.
In 2008, I did 1h59m19s, 2009 1h57m07s. This year, I manage to do 1h47m45s. almost 10 min faster or 28sec/km faster than 2009.
It's funny, because I had a bit less training than 2009, but different shoes. But seriously, I think this year the cool weather helped. Maybe I did a bit more interval training than previous years, that maybe helped a bit.
So I manage to keep a pace very close to 5min/km. Here's a graphic of my pace at every km and on top the elevation profile of the course.
You can see the path we took around Ottawa and Gatineau on the Québec side here.
One thing I did a bit better this year was hydration. I drank quite a lot of fluids and electrolytes in the 24hours before the race. I also took a pack of gel (shot block) 1 hours to 30 minutes before the start. During the race, I drank 75% Gatorade and 25% water and a gel at around 9km. I had on myself a small 5oz bottle of water mixed with electrolytes that I took in the last 5km. The last 2 km where hard with my feet getting soared and tired. I finished with thigh calf but happy about my time.
The Ottawa race weekend is a very well organized weekend with many thousand people. I big party of people in good shape.
