What is Paul referring to specifically that he hasn’t taken hold of?
Phil. 3:8 ἀλλὰ μενοῦνγε καὶ ἡγοῦμαι πάντα ζημίαν εἶναι διὰ τὸ ὑπερέχον τῆς γνώσεως Χριστοῦ Ἰησοῦ τοῦ κυρίου μου, δι᾿ ὃν τὰ πάντα ἐζημιώθην, καὶ ἡγοῦμαι σκύβαλα, > ἵνα Χριστὸν κερδήσω > 9 καὶ εὑρεθῶ ἐν αὐτῷ, μὴ ἔχων ἐμὴν δικαιοσύνην τὴν ἐκ νόμου ἀλλὰ τὴν διὰ πίστεως Χριστοῦ, τὴν ἐκ θεοῦ δικαιοσύνην ἐπὶ τῇ πίστει, 10 τοῦ γνῶναι αὐτὸν καὶ τὴν δύναμιν τῆς ἀναστάσεως αὐτοῦ καὶ [τὴν] κοινωνίαν [τῶν] παθημάτων αὐτοῦ, συμμορφιζόμενος τῷ θανάτῳ αὐτοῦ, 11 > εἴ πως καταντήσω εἰς τὴν ἐξανάστασιν τὴν ἐκ νεκρῶν. > 12 Οὐχ ὅτι ἤδη ἔλαβον ἢ ἤδη τετελείωμαι, διώκω δὲ εἰ καὶ καταλάβω, ἐφ᾿ ᾧ καὶ κατελήμφθην ὑπὸ Χριστοῦ [Ἰησοῦ]. 13 ἀδελφοί, ἐγὼ ἐμαυτὸν οὐ λογίζομαι κατειληφέναι· ἓν δέ, τὰ μὲν ὀπίσω ἐπιλανθανόμενος τοῖς δὲ ἔμπροσθεν ἐπεκτεινόμενος, 14 κατὰ σκοπὸν διώκω εἰς > τὸ βραβεῖον > τῆς ἄνω κλήσεως τοῦ θεοῦ ἐν Χριστῷ Ἰησοῦ.
P.T. Obrien (NIGTC 1991) lists several options:
τὸ βραβεῖον
εἴ πως καταντήσω εἰς τὴν ἐξανάστασιν τὴν ἐκ νεκρῶν.

everyhing bewtween 8-11
ἵνα Χριστὸν κερδήσω
Resurrection from the dead, apparently, cf. 11, where he expresses his hope of attaining that (cf. 14, “God’s call up in J.C.”). But it’s not easy to pin Paul down, as the proffered list of “options” demonstrates, and like many preachers he doesn’t care too much about internal consistency. In 12 he says he’s not teleios, in 15 he implies that he is. The writing is forceful but we have to impose coherence upon it — or not (but commentators routinely do, or try to).
