Caiff y Great River Race ei hadnabod Marathon Afon Llundain; ras 21.6 milltir o dan 28 o bontydd o Millwall yn y dwyrain i Richmond yn y gorllewin.

The Great River Race is billed as London’s River Marathon; a 21.6-mile race under 28 bridges from Millwall in the east to Richmond in the west.

Gan fod llawer yn gweld Ras Ynys Seiriol fel eu hoff ras o'r tymor, doedd dim syndod bod uchafswm o 24 o gychod wedi cychwyn y ras eleni.

Seen by many as their favourite race of the season, it was no surprise that a field of 24 boats took to the start line of this year’s Puffin Island Race.
