Your pace band
Tell us your goal and we give you every kilometre split, already adjusted to the hills of this course: a few seconds more where it climbs, a few less where it drops, the same effort all the way. Print it and wear it on your wrist.
Your gel plan
Tell us how many carbs you want per hour and what each gel carries. We tell you at which aid station to take each one, so you wash it down with water instead of dry.
The organisers hand out gels at these points (Finisher): km 19, 23.5, 28.3, 36.
