Thank you for your answer. I don't know about と, but about までも, doesn't it emphasize just as much as も? In the two examples from the dictionary, they seem interchangeable.
全部で一〇〇円までもかからない = 全部で一〇〇円もかからない
一〇〇キロまでも走らなかった = 一〇〇キロも走らなかった
Though I don't think they are interchangeable in the last example. 5分までも走らないうちに息切れしてしまった sounds wrong due to 5分までも走る.
