  Tip of the red giant branch distances are acquired from Hubble Space
Telescope images for 16 galaxies to the foreground of the Virgo Cluster. The
new distances with 5% accuracy, combined with archival measurements, tightly
constrain the near side location of the onset of infall into the Virgo Cluster
to be 7.3+-0.3 Mpc from the cluster, reaching within 9 Mpc of the Milky Way.
The mass within this turnaround radius about the cluster is 8.3+-0.9 x 10^{14}
Msun. Color-magnitude diagrams are provided for galaxies in the study and there
is brief discussion of their group affiliations.
