For an average jogger, completing the approximately 6.6 km (4.1 miles) round trip with significant elevation gain can take around 1 hour and 3 minutes, as indicated by komoot's estimates. However, this can vary greatly depending on your fitness level and how often you stop to enjoy the views.

The initial mile is often cited as the most demanding due to its steep grade. Pacing yourself from the start and taking advantage of the numerous switchbacks can help manage the climb. After reaching a saddle, the trail may offer some flatter sections or even short descents before the final push to the top, providing brief respites.
