Unfortunately so, most of the others are posting on here saying how unfit they are and that this is going to kill them. Most of the training appears to be in the format of drinking bear and eating cake. Very little running is being done.
What time did you run SD in Lorra? I would imagine that your GH time will be similar.
I tripped on a tree root a while ago, injured my knee, ankle and ribs. Couldn't run for a couple of weeks. I do hope your injury is not bad, if it's just bruising you should be fine. Don't know how I tripped, landed flat on my back.
