Finished the HM in 1:32:xx.... slightly disappointing....
My 'cool weather' HM is 1:27 and I was hoping to get 1:29-1:31 in Singapore, taking into account the temperature differential. At the end, it wasn't the temperature that was the main problem, but it was the 'traffic congestion' that slowed me down.
The event was just too big - 40,000 runners participating in the 42k, 21k, and 10k. The marathoners started at 5:30 while the half-marathoners started at 6:15.
Was doing Ok for the first 6k, averaging 4:18 min/km. After that, I started to catch the slow runners and walkers (5-7 hours marathoners) and had to zig-zag my way through for the next 10k. During this segment, my pace slowed down to 4:28 min/km - a lost of almost 2 minutes. I couldn't count how many times I got bumped left and right because I was trying to navigate my way through.
After 16k, we had a turnaround point and it was free traffic from there. My pace improved to 4:16 min/km for the last 5.1k . However, I couldn' run any faster as my hip began to get very tight and the mercury began to heat up.
Garmin GPS measured total distance as 21.74 km (av. 4:16 pace). I think the zig-zaging during km 7-16 led to the extra distance.
I think the organizers should design a different route for HM-ers in order to prevent 'bottlenecking'. Also, slow runners should learn race etiquette by keeping left at all times. Met the 11th place finisher from Australia at the finish. He has a PB of 1:13 and finished the HM in 1:24. He was very disappointed with the organization and lack of discipline/knowledge of slow runners.
Otherwise, a good flat course and nice weather for Singapore standard.Well done to all !
