The Monster Sportive.
The Monster is not your average sportive. It is aimed at experienced riders who are bored of the standard, easy sportive events out there. It is for riders who know that total climbing is much harder than distance, and for those who think a standard 100 miler is a walk in the park. It is small in terms of participation numbers, but has a friendly vibe and the 2014 was ranked as one of the top sportives on Cyclosport.org.
