Seizing up on long runs :

"Hi Marius,

I've been enjoying the Sub 3:30 plan. I'm in week 8 and I ran the walk 30 run 2:30 easy long run. Basically, I'm keeping the on 1 alright but after about 23K my legs really began to seize up. Do you think this is a hydration or salt issue (or something else?).

Answer: Hi Rob and thanks for your question.

You want to read this article I wrote on cramps - it is relevant to your situation as well :

In addition to this tip, do test out compression socks - some runners have really good experience with this, to solve your problem.

I wish you all the best,
Marius
