Keji's Backyard Ultra happens at Kejimkujik National Park and National Historic Site!?!? Sweet!! This lovely, scenic and tame 6.67km course follows either the Mersey River or Kejimkujik Lake for 70% of the loop! 4.7 km of non-technical gravel single track, 1km of pavement and 1km of gravel road…and only ~40 metres of elevation gain/loss per loop! How hard can it be to run for a few days!? 🙂 No time limit. This is truly a “last person standing” event!
