The Monster Cross looks really fun! 50 miles sounds intimidating but I know I could handle the 21 miler. Our wedding anniversary is that Saturday but maybe we could turn it into a weekend getaway and do something fun Saturday night. I'm going to bring it up to hubby tonight. I'll also check out the other links you posted.

I have never done the Wild Goose Chase before but have been planning on it for this year. However, I just found out that the St Michael's Running Festival is also that weekend, so I might run in that on Saturday instead and just do the fun ride on Sunday.
