The total elevation gain for the 100k will be in the ballpark of 6,000ft and around 11,000ft for the 100 miler. For this year, we can only give an approximate estimate of the elevation gain prior to the running of the event. It is especially difficult to get an accurate reading with all of the ups and downs and winding that take place on top of the mesas. Be warned: your body will feel a lot more beat up than the elevation profile tells you. Sections of the course (Gooseberry and Guacamole) are especially difficult and leave experienced runners scratching their heads afterwards wondering why they feel so much more exhausted than the elevation and distance on their watch reads.
