Juanl, we don’t have an Xterra version of our plans. I have frequently recommended that athletes use our regular plans and consider “leveling up” to a level higher to accommodate the additional demands/time required for an Xterra. If you would normally use a Level 1 plan, use a Level 2 plan. Since our plans primarily use time and not distance, this adjusts for the longer time required off-road. I’ve received several comments back that this worked from athletes, but I’m not sure it is the best option. I make the recommendation with some hesitation.
