Spent or exhausted beforehand; having expended energy or resources in advance.
From 'fore-' + 'spent' (past participle of 'spend'). The 'for-' prefix indicates the exhaustion happened at an earlier time, before some anticipated moment.
Forespent captures a specific kind of tiredness—not tired from what you're doing now, but already worn out before you even started. Athletes call this 'going in flat.'
