Course Planner Graham Atkinson gives us the low down in this 54th OMM, Eryri blow-by-blow report. Great insight from an expert!
Wednesday Workout – James and Sam tackle unfamiliar territory with a interval track workout, how useful is a track workout for mountain running?
12 x 400m:
Warm Up 5 – 10 minutes easy jog:
Just get the body moving and heart rate elevated
1km Threshold:
This is a pace you could hold for a maximum of 1 hour. 1km at this pace should feel nice and sustainable and is a good way to prepare for the harder efforts ahead.
12 x 400m (with 60 seconds standing rest recovery):
Aim to be slightly quicker than your target 5km race pace on these. 400m at this pace should feel hard but after 60 seconds of rest, you should have your breathing under control and feel ready to go again. You might start to feel the effort towards the latter repetitions, concentrate on staying relaxed and maintain good form.
1km Threshold:
This pace might feel strangely slow after 400m efforts but it’s great to flush out the lactic acid that the efforts will have produced.
Cool Down 5 – 10 minutes easy jog:
Job done, time for a cuppa *OMM is not a qualified coach but we do run quite a bit and these kind of workouts seem to work for us!
Do not attempt a hard session if you do not already have a good training base. If you are new to running or are just building mileage back up, concentrate on lots of steady and easy runs rather than pushing pace in a session.
