The \\emph{average stretch factor} of $G$ is the average stretch factor taken over all pairs of vertices in $G$. We show that, for any constant dimension, $d$, and any set, $V$, of $n$ points in $\\mathbb{R}^d$, there exists a geometric graph with vertex set $V$, that has $O(n)$ edges, and that has average stretch factor $1+ o_n(1)$.
