Training Plans and Support for Novices planning their first half marathon, marathon, ultramarathon or triathlon.
I've been racing endurance sports since 2009... Everything from Ironman to Sprint Duathlons, I've also completed the Comrades Marathon (world's largest UltraMarathon!) and numerous ultramarathons.
Time, heart-rate, and power based workouts are what I think are the keys to success.
And a perserverence!
