To that I would say if you’re (@konass) following the XC plan, you should have some pretty good ideas on some workouts. Those race-start will let you know where you stand, but doing some 30s to 1 min all out efforts with complete recovery in between might be something for you to focus on for 2-3 weeks. Don’t try to really even pace them that much, but go all out to really stress your anaerobic system.
