NET
25 Each competitor must exercise self-control in everything. They do it to receive a perishable crown, but we an imperishable one.
Darby
25 But every one that contends [for a prize] is temperate in all things: *they* then indeed that they may receive a corruptible crown, but *we* an incorruptible.
KJV
25 And every man that striveth for the mastery is temperate in all things. Now they [do it] to obtain a corruptible crown; but we an incorruptible.
