If a session has been purchased, then the trainer who can access a report of the complete data generated during a session.  An example report is shown here.  

The report illustrates where the horse ran on a satellite image, details the full session stats and shows a graph of heart rate and speed throughout the session.  A second graph shows an expanded view of the session as the horse progressed through the timing points on the track.  Each of the shaded sections represents each of the sections between timing points.  The stats for each lap including max speed, max heart rate and sectional times are detailed.  

If the horse runs multiple laps or breezes, then a separate graph and table of sectional data is shown for each lap.  There is no limit to the number of sessions which can be run in a single session.  Each time the horse crosses the finish line a lap is completed.
