My fourth half-marathon. Not quite a personal best, and my excuse is that the course is a bit up-down hilly and has a lot of turns that slows you down.
Otherwise a solid run with no major problems. A lot warmer than last year, so I ran in shorts and T-shirt. I could put in some work on the uphills which made the HR go >170 and still recover to a reasonable HR 165 or so on the downhills or the flat bits.
My own garmin said 1:53:00, the chip time on the results website seems to be 1:52:57, and the time from the gun was 1:54:14.
The 5k times were: zero to 5k in 28:24, five to 10k in 26:30, ten to 15k in 26:09, fifteen to 20k in 26:25. In other words first 10k in 54:54 and the second 10k in 52:34.
Update: here's the GPS-trace.
