I think I walked about 1.8k. So it was .3k warm up; 4k run; 1k walk; 3K run; .5k walk; final run was about 1.2k. So not a continuous run, and the final 2k felt somewhat slower. Fastest 1k was 11:15, slowest was 12:19 (probably because I walked a bit of it) and the 6th 1K was seriously unpleasant running through the stinky area with many vehicles, roadworks and funky urban smells. I did plan to ride a Youbike back but I was knackered by the winds running towards Taipei.
