0-5km

Given the fact that I have been nursing a strained groin on the right side started carefully. Favorable weather and a sparsely crowded start line meant that I could ease into the run gradually in these initial KMs. Found a steady rhythm and decided I’ll stick to it through the race.

Timing Mat split @5kms – 22m:25s, 4:29 mins/km

6-10 km

– This section was relatively flat and by now the body had warmed up. Crossed a few familiar faces from the Bangalore running circuit in this section without expending much of energy. This was also the section where I dropped a gel.

Timing Mat split @10km – 44m:48s, 4:29 mins/km

11-15 km

This was an interesting and challenging section BOTH. Andy who I had crossed initially in the race crossed me after the halfway mark. We had a flyover in this section and my left quad tightened up a tad bit as it has on inclines for some time now. I put my head down and focused on the runner ahead as I crossed the flyover and regained my mojo.

Timing Mat split @15km – 1h:07m:26s, 4:30 mins/km

16-20 km

The initial part of this section involved a straight tree lined sparsely crowded stretch and that was followed by a stretch that went through a crowded market place with a small bridge. In the initial section Andy’s white cap was an excellent beacon that guided me and in the latter section the energy of the crowd around made me tide over the fatigue that was building up. I reeled in a few more runners in this section and I stuck to the blue lines at the turns to minimize running extra kms.

Timing Mat split @20kms – 1h:30m:30s, 4:32 mins/km

21-25 km

This for me was the best section of this race. In-spite of fatigue that had built up in the previous section I was able to regain my composure and come back strong. One runner did reel me in, but my focus was on the runner ahead of me and when I reeled him in the next runner ahead of me and so on. A familiar script played out here which is worth a mention – Madat Brahma (pacemakers) overtook me with about 2 kms to go and then I overtook another runner from Chennai with about 600m to go. I could also see Andy’s white cap in the last kilometer and that meant he was slowing down. I finally crossed that one runner who overtook me in the initial part of this section. All these cat and mouse games motivated me to run my fastest kilometer to the finish line. The fact that you could see the finish line through the last 1km also helped me to push in that final km.

Timing Mat split @21.1kms – 1h:35m:20s, 4:32 mins/km
Timing Mat split @25kms – 1h:52m:59s, 4:32 mins/km
