Ar Hydref 12, byddaf yn gwireddu un o'm dymuniadau bywyd - trwy geisio ymweld a phob un gorsaf ar Dren Tanddaearol Llundain gyda'm cyfaill, Simon Harburton. Bydd yr her yn cymryd oddeutu 17 awr - 0 5 y bore tan hanner nos!

On October 12, I will be completing something on my life "bucket list" - to do the "Tube Challenge" by trying to visit every single station on the London Underground network within a day with my friend, Simon Harburton. The challenge will take around 17 hours - from 5am until midnight!
