Last March 17, 2013, thousands of runners converged at the SM Mall of Asia grounds for the biggest running event of the year, the Unilab Active Health and RunRio’s Run United 2013 series. Jeff and I started preparing for this race since January with weekly runs at the UP Diliman grounds. Jeff is the one with the most preparation because he ran his first 21 km, while I only registered for 5 km.
