Vertical running might be a thing in the future- or at least an attempt at it. For now? He gets close to the base of the cliff and vaults up, hands out stretched for the first outcropping to haul himself up. Or. Fling himself higher, as it turns out.

Cackling with glee he bounds from point to point till he's at the top, only then whirling around to peer where he's surely left Locus standing and staring after him-

Only to see a blur heading in his direction. Oh. Shit! He sprints along the cliff face, trying to regain the time he's lost by looking backward.
