Well why not? 28 minutes is hardly any different than 30, right? For that matter when you remember 1 minute being a struggle, surely there's hardly any difference between 20 minutes and 30?
It turns out that that 2:30 was quite a struggle. I don't know if it was just the psychological impact of running after I had been told I could stop or whether the program is very cleverly designed to push you only to the edge of your ability and no further. I suspect the latter. Always trust the program! It seems to be cleverer than me, at least.
Still, I was pleasantly surprised to find that after that exhausting 30:30 I was only about as tired as I remember being after Week 1. That's a huge improvement! Less than 2 weeks and I should be a graduate at last
It also ticks off the first goal I set for myself - to run for 30 minutes - and puts me on track to finish my second, running 5k in 30 minutes. Since week 2 I've consciously decided not to measure the distance of my runs, but once I graduate I think I will go for a measured 5k and see how long it takes.
