I believe this was the race course for the 2011 UCI MTB World Cup XC!
Need to Know
Be aware that there are so many trails in this park and along the way that it is very easy to take a wrong turn so make sure to follow the map carefully.
This is my favorite and one of the hardest loops I have found in Casa de Campo. Most of it is smooth singletrack that any average rider can ride but it's some of the uphills and downhills that will challenge you. They aren't long but steep enough to make it difficult.
There is one downhill that will separate the boys from the men or the girls from the ladies...depending on the weather it could be harder than normal due to it being slippery with dust/dirt or mud.
This can be fun ridden in both directions but probably more fun and ride-able clockwise.
