The nuance of ことなく compared with ないで?

Question

What nuance does "ことなく" have? If we compare the following two sentences: (For example, at a footrace:) 最後まで、あきらめないで走ります！ vs 最後まで、あきらめることなく、走ります！ Is ことなく stronger than simply saying ないで? Does ことなく show will and volition more than the ないで version?

Answer 1

They are exactly the same. They are just different ways of saying it.
