The Muon g-2 experiment will measure the precession rate of positive charged muons subjected to an external magnetic field in a storage ring. To prevent interference in the magnetic field, both the calorimeter and tracker detectors are situated along the ring and measure the muon's properties via the decay positron. The influence of the magnetic field and oscillation motions of the muon beam result to parts per million corrections in the muon precession rate. The tracker detectors are designed to precisely measure the profile of the muon beam. The Muon g-2 software uses Fermilab support framework, "art", to manage the data handling and organization of the tracking algorithms. A sophisticated tracking infrastructure is needed to execute efficient and multiple algorithms performing hit pattern recognition, track fitting, and track extrapolation of the decay positrons. In addition, the framework handles the linkage and coordination of data between the tracker and calorimeter detectors. The tracking software takes advantage of all available resources to reconstruct high quality tracks for understanding the beam profile of the muons in the g-2 experiment.
