Although Nathan is too young to qualify as an athletics coach he has been assisting on 2 evenings a week with the coaching of very young athletes with Amman Valley Harries in Ammanford.
Er bod Nathan yn rhy ifanc i gymhwyso fel hyfforddwr athletau, mae wedi bod yn rhoi dwy noson yr wythnos i helpu i hyfforddi athletwyr ifanc iawn gyda Harriers Cwm Aman yn Rhydaman.
