Up to you mate. (and I don't mean that to sound flippant or harsh
)
I stand by what I said, because it's true. If you have a medical condition that makes it difficult for you that's neither here nor there in the context of the discussion. Like I said, if all the above apply, then it
should be a doddle. Alright, perhaps I could have added "and have no underlying medical conditions that would prevent you from passing it" to my assertion but frankly, my post was meant as a generic intention. You've managed to make it about you.
Being able to run 2.6km in under 12mins is nothing special for anybody 35 or below. If you can't then ad infinitum ... etc.
