How slow is slow? When it comes to finishing Comrades

On this edition of the Ask Coach Parry podcast and the question was submitted via our website, askcoachparry.com. Nicole got in touch said she'll be running her first Comrades come 31 May. She’s got two main concerns for race day though. The first one is, how to avoid cramping, and the second, how slow is slow? Her qualifying marathon was a 4:46 and she says she can comfortably run at 7min, 7m30s a kilometre but she's still afraid of not starting slow enough or starting too slow that she ends up not making it through the cut-off point. So I think it's a valid concern, particularly that second question. Lindsey, what's your thought?
