M87 is a giant radio galaxy located in the Virgo Cluster, known to be a very\nhigh energy (VHE) gamma-ray source. As radio galaxies are considered the\nmisaligned low-redshift counterparts of blazars, they are excellent\nlaboratories for testing AGN emission models. M87 has been detected and\nmonitored by Fermi-LAT and several atmospheric Cherenkov telescopes. Recently,\nthe HAWC Collaboration presented marginal evidence of 4.5 year TeV gamma-ray\nemission from this object. The HAWC data has the potential to constrain the\naverage VHE emission of sources of complex behavior, like M87, for which the\nphysical origin of the VHE gamma-ray emission is still uncertain. We fitted a\nlepto-hadronic scenario to the broadband spectral energy distribution of M87 to\nmodel its non-flaring VHE emission using HAWC data.\n
