Fe wnaeth Guto deithio i Lesotho pan yn 9 oed gan fwynhau a gwneud ffrindiau oes.
Mae rhedeg Marathon Llundain yn cyfuno dau o’i hoff bethau- cefnogi Dolen Cymru a rhedeg ei farathon gyntaf!
Guto visited Lesotho when he was 9 years old where he made lifelong friendships and enjoyed himself. Running the London Marathon means he can combine two things he loves- supporting Dolen Cymru and running his first marathon.
