TRGB distances to galaxies in front of the Virgo cluster
  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.
