IT is VERY hot and humid right now where I live - on Tuesday morning around 5AM, I set out to run 6Klms at 7:00 mins perK using 90sec/30sec run/walk intervals. That 42 minutes had me soaking wet at the end!! So this morning, I thought I would do something different. Because I feel that I have been struggling with the Singapore-like weather, I planned on doing a shorter run with a bit of a warmup followed by 3x 1klm non-stop repeats at a pace faster than my absolute 5K PB average pace - with sufficient rest inbetween each repeat. It was a challenging workout and I finished up running faster during each repeat that I had planned to and the average of those three repeats was 5:30 mins per k-- which would equate (if I had sufficient stamina to do so) to a 5K of 27:30. It was a good hard workout - more so because of the weather - and I think I will do this once per week from now on. I have kind of done this before - but only 400 metre repeats with lesser time rest inbetween. The 1Klm's felt more of a challenge.
