The Milton Keynes Winter Half Marathon is AIMS measured and UKA licensed, meaning it has a certified course. However, it is only a qualifying event for the London Marathon Good For Age (GFA) entry if you have first achieved a qualifying time in the TCS London Marathon MyWay (Virtual London Marathon).
How it works:
✅ If you ran the TCS London Marathon MyWay within the required Good For Age (GFA) qualifying time, you can apply for a GFA place.
✅ Since virtual marathon times alone do not qualify, you must also submit proof of an ‘in-person’ half marathon time that meets the required standard.
✅ The Milton Keynes Winter Half Marathon meets the certification requirements and can be used as your in-person half marathon result—as long as you run it within the qualifying time and period set by the London Marathon.
✅ Check the official Good For Age qualifying times and full details here:
