Given a Lipschitz stratification $\mathcal X$ that additionally satisfies condition $(\delta)$ of Bekka–Trotman (for instance any Lipschitz stratification of a subanalytic set), we show that for every stratum $N$ of $\mathcal X$ the distance function to $N$ is locally bi-Lipschitz trivial along $N$. The trivialization is obtained by integration of a Lipschitz vector field.
