We study the problem of chasing convex bodies online: given a sequence of convex bodies <?TeX $K_t\subseteq \mathbb {R}^d$?> the algorithm must respond with points <?TeX $x_t\in K_t$?> in an online fashion (i.e., <?TeX $x_t$?> is chosen before <?TeX $K_{t+1}$?> is revealed). The objective is to minimize the sum of distances between successive points in this sequence. Bubeck et al. (STOC 2019) gave a <?TeX $2^{O(d)}$?>-competitive algorithm for this problem. We give an algorithm that is <?TeX $O(\min (d, \sqrt {d \log T}))$?>-competitive for any sequence of length <?TeX $T$?>.
