I dabbled here at NF for a while but never got involved, mostly just skimming for ideas. I've not at all been able to keep on track with fitness goals for the past few years, or any goals for that matter. As such I'm looking to fully enter the adventure community here. Any ideas on what to begin to prepare for the next 4 week challenge? I wish I could have gotten in before the end of the current one
