Easter Backpack Plans: Knighton to Abergavenny along the Offa's Dyke Path

I'm currently sat on a train to Knighton, from where I'll shortly be starting to walk south on the Offa's Dyke Path for 3-4 days. The plan at present is to walk to Kington today and then onto Hay-on-Wye tomorrow. Then ideally on Sunday I'll walk over the Black Mountains to Pandy, but I'll wait and see what the snow conditions are before finalising my onward route from Hay-on-Wye. All being well I should arrive into Abergavenny sometime on Monday.
