SAFRA Singapore Bay Run & Army Half Marathon 2012

This was my third time participating in SAFRA Singapore Bay Run & Army Half Marathon, and 2nd time ran in barefoot. I have been using this traditional event as my annual 21k time trial because of it's good organization and sanctioned distance (although last year we thought is was over 0.7km shorter). One week before race a strong haze hovered over Singapore's sky, with PSI and PM2.5 both rising over 50. Fortunately a big shower cleared all this away the night before the race, bringing also a cool weather.

I woke up at 3:30am and reached The Padang around 4:40am and had my bag deposited very quickly because there were plenty of NS men at our service. But I surprised to find long queues in front of mobile toilets, maybe due to insufficient toilets supplies this year. I gave up and made my way to the Esplanade Bridge starting point. This year the organizer reserved a passage for "seeded runners" (elite runner I think) to get to the front of the starting line. I joined the less privileged runner in another long queue to move onto the bridge. In the past I could use the pavement of the bridge short-cut to the front, but this year it was blocked. I had to stay about 200m away from the starting line and later it took me 2min to move past it.

Flag off was punctual as usual at 5:15am sharp. 1st 2km in Robinson Road Shenton Way was same as last year, the parade moved slowly and I took it as warm up at a pace of 6:43/km. There was pauses at each of the turning point, no matter in the road or PCN. After 3km we turned to Marina Bay Boardwalk passing through newly opened Gardens By The Bay. But in the dark we could see nothing. The running experience was much better in the PCN leading to Marina Barrage, compare with previous "Marina ST- Marina- Place- Marina Mall" route which was a part of transportation line for Marina East/ South construction, dirty and rough. After 5km mark we moved to Marina Barrage, it was already 31min and I could move no faster then 5:45/km pace. The following 3km stretch of PCN at Marina East was also narrow. It would took more energy to weaving among the people. I avoided to do so and slowly overtook people, through it was 30s slower than my target pace. I was not the only impacted one, at 6km I overtook 2:00 pacers, they also fell behind their target timing a lot. I kept it to 8km mark, then I start to pump up to 5:15/km pace, on the meadows beside the PCN of Tangjong Rhu.

When I reached 10km turning point it was already 58min. Good news is we were back to the road, and the crowd was smaller after 1hr's overtaking. Very natural. The I decided to push a little bit and geared up to 5min/km pace, even when climbing up Tanjong Rhu Bridge. When we turned from Mountbatten Road to the wide, straight and flatten stretch of Nicoll Highway after 12km mark, very good for overtaking. I sped up to 4:50/km, and decreasing by 10s/km every 2km, while other people were getting slower and slower. The speed fun was interrupted after turning into Kampong Bugis at 16km mark, the road surface was so rough and even though it was down slope I decelerated to 5min/km pace. The 1km stretch tortured my soles but it was alright since I had put 1800km+ barefoot millage on them. The bridge in Kallang Riverside Park at 17km mark was so narrow (a pedestrian crossed bridge in a park, what do you expect? ) later turned out to be the most stringent bottle neck, after the massive 21k and 10km runners merged together. I was lucky to pass without delay because most runner had not been there.

Then we were again away from the main road, ran on Marina Promenade along Kallang river. Through I didn't like the pavement, I kept 4:40/km pace. At 18km mark, we turned into F1 track at which I was astonished to find all asphalt gone, only gravels left! It was quite different to that I ran J.P. Morgan 5.6k in Apr. I wondered if it was next week's GP F1 night race requirement. The 2km track was real challenge to my barefoot. I'v anticipate it to be rough base on previous experience, not expecting it to be so worse. I did not reduce cadence, just change mid-foot landing to "whole-foot" landing to ease the impact, my pace maintained steady without deceleration. The ultimate torture was over in 9min, at 20km we turned into Esplanade Drive. I started to sprint, pace increased from 4:30/km to 4:10/km. I also turned the tempo trainer (YAMAHA ME55BK clip on metronome) which help me to maintain 180/min cadence, striving for a free run. Before entering Pandang, I noticed my average pace reached 5:16/km, I almost hit my target pace, and also meant I would get a PB this time (Last year I ran 1:52 in 5:19/km pace, though it fell 700m short). I finished in 1:51:15, based on my Garmin305.

The distance was accurate, my watch shown 21.11km. I believe the course was sanctioned on IAAF criteria, as the organizer claimed. I think my last year timing should be 1:56 had not been the course falling short. So this year I'v improved by 5min. Thanks for the MAF training I dedicated since last December. My boy was comfortable throughout the race, starting in a slow pace with prolonged warming up, speed steadily increase to the end of the race. And my bare soles were also seasoned and could deal with tougher surface, without blisters and worn out. I hope I could ran into 1:45 next year.

The medal was nice too, compare with last two years. I notice there was a mark of "ELM" on it, same as Standard Chartered one, very good design and quality.

Official timing was out, 1:51:13. The Runpix analysis shown that I had passed 295 runners during last 5km, second to another runner who passed 303. Both us ran a reverse pyramid scheme. I was forced to because the human wall, what about this guy?
