noun
Rare term for running a long distance without stopping; often implies a sustained dash or continuous run.
彼は駆け通しで丘を越えた。
He dashed over the hill without stopping.
More common term for a full-speed sprint, while 駆け通し emphasizes the continuous, long-distance aspect of the run.
Compound of 駆け (kake, 'running') + 通し (tōshi, 'through, continuously'). The exact historical derivation is uncertain, but the word is formed from common elements.
