We consider subleading power corrections in the $\\tau \\ll 1$ expansion, and employ soft-collinear effective theory to obtain analytic results for the dominant $\\alpha_s \\tau \\ln\\tau$ and $\\alpha_s^2 \\tau\\ln^3\\tau$ subleading terms for thrust in $e^+e^-$ collisions and $0$-jettiness for $q\\bar q$-initiated Drell-Yan-like processes at hadron colliders.
