Whooo that is rough, 30F. I’m use to 72F in winter and 105F in summer where I live. So I don’t know how you train in those conditions, the North American and European guys will be able to help. I would think that you do all your training indoors, but I guess thats not quite possible.
I wouldn’t do Acc before a meet I think the CNS strain would be to big, rather use the meet itself as Acc Dev.
