While the first and last 5 go 6 km of this run aren't the most exciting, the views are well worth it once runners reach the beautiful meadow and the alpine terrain above. Dramatic views of Mount Peter Lougheed are to be expected. Don't forget warmer clothes for the summit and keep in mind that weather can change incredibly quickly in this area.
