  We establish the sharp rate of continuity of extensions of
$\mathbb{R}^m$-valued $1$-Lipschitz maps from a subset $A$ of $\mathbb{R}^n$ to
a $1$-Lipschitz maps on $\mathbb{R}^n$. We consider several cases when there
exists a $1$-Lipschitz extension with preserved uniform distance to a given
$1$-Lipschitz map. We prove that if $m>1$ then a given map is $1$-Lipschitz and
affine if and only if such distance preserving extension exists for any
$1$-Lipschitz map defined on any subset of $\mathbb{R}^n$. This shows a
striking difference from the case $m=1$, where any $1$-Lipschitz function has
such property. Another example where we prove it is possible to find an
extension with the same Lipschitz constant and the same uniform distance to
another Lipschitz map $v$ is when the difference between the two maps takes
values in a fixed one-dimensional subspace of $\mathbb{R}^m$ and the set $A$ is
geodesically convex with respect to a Riemannian pseudo-metric associated with
$v$.
