It's true, the course is changing to avoid some particularly damaged trails. Unfortunately, the last wave of storms tore up one of the longer sections (turtle trail, around the fire tower for those that are familiar). The good news is that we're able to work with the park and have a revised loop in mind which looks to be around 7 miles - so likely a 1, 2, 3, lap format for xc. We're still using a lot of the same great trails. The new course is riding very well and will still be a ton of fun.
I'm not sure which hike-a-bike sections you're talking about... There's obviously some climbing but it's all rideable.
