Gwyn oedd yn sefyll ar ddechrau llwybr hir ac anodd yng Ngwlad Eryri.

Gwyn was standing at the beginning of a long and difficult path in Gwlad Eryri.

Roedd yr hydref yn ei ogoniant llawn, gyda’r dail aur a rhwd yn pefrio yn erbyn mynyddoedd garw'r parc cenedlaethol.

Autumn was in its full glory, with golden and rust-colored leaves sparkling against the rugged mountains of the national park.

Roedd gwynt ysgafn o aeaf yn chwythu dros y llethrau, gan gario arogl cynnar o rhew.

A gentle winter breeze blew over the slopes, carrying a faint scent of frost.

Roedd Gwyn yn edrych i fyny at yr uchelderau, uchelgais yn amlwg yn ei lygaid.

Gwyn looked up at the heights, ambition clearly visible in his eyes.

"Mae'n bryd," meddai wrth ei ffrind Brynn, sefyll wrth ei ochr.

"It's time," he said to his friend Brynn, standing beside him.

Roedd Brynn yn gwybod bod hyn yn fwy na dim ond taith gerdded arall i Gwyn.

Brynn knew this was more than just another walk for Gwyn.

Roedd Gwyn wedi cael diagnosis iechyd yn ddiweddar, a bellach roedd yn benderfynol i brofi ei hun - i’w hun ac i bawb arall - nad oedd ei gorff wedi'i drechu eto.

Gwyn had recently been diagnosed with a health condition, and he was now determined to prove to himself—and to everyone else—that his body had not been conquered yet.

"Bydd yn anodd," rhybuddiodd Brynn yn dawel, yn edrych ar y tirwedd llithrig o flaen nhw.

"It will be hard," Brynn warned quietly, looking at the treacherous landscape ahead of them.

Gwyn wnaeth wenu. "Rhaid i mi brofi fy hun," eglurodd gwên llwm.

Gwyn smiled. "I have to prove myself," he explained with a grim smile.

Gyda hynny, dechreuon nhw gerdded, eu traed yn symud yn raddol dros y llwybr creigiog.

With that, they began to walk, their feet gradually moving over the rocky path.

Wrth i'r noswyl syrthio, llwybrau niwlog yn dechrau ei lapio fel straeon hen.

As dusk fell, misty paths began to envelop them like old stories.

Roedd calondid Gwyn yn y brwydro, ond erbyn iddi fynd ar uchderau newydd, roedd y ddawn i godi ei traed yn dod yn gloff.

Gwyn's courage was in the struggle, but as he reached new heights, the ability to lift his feet became sluggish.

Roedd gorffwysbyn Gwyn yn brin; cysylltiad â’r ddaear oedd ychydig yn llonydd.

Gwyn's rest points were scarce; the connection to the earth was a bit still.

"Teimla i’n..," dechreuwyd Gwyn broffio’i fol.

"I feel..." Gwyn started, clutching his stomach.

Roedd ganddo boen yn y frest a dechreuodd wynto’n frysiog.

He had chest pain and began to breathe rapidly.

Ond er bod Brynn wedi cynnig stopio, gwrthododd Gwyn.

But even though Brynn suggested stopping, Gwyn refused.

Yi prancio oedd pwysicaf, meddai Gwyn wrth ei hun, gan orfoledd yn euopibio’r mwyaf.

The prance was most important, Gwyn told himself, delighting in the euphoric sprint.

Yn ei ffon cefndir, daeth cwmni arall - Carys, profiadol a’r llongoryn gofalgar.

In his background, another company came - Carys, experienced and the caring navigator.

Daeth rhaid i Gwyn wynebu’r gwirionedd ddigalon: roedd yn rhaid iddo stopio.

Gwyn had to face the disheartening truth: he had to stop.

Pan oeddent bron ar ben y ffordd, daeth cyflafan o boen ddisymudwn i’w guddio.

When they were almost at the top of the path, a sudden wave of pain came to conceal him.

Yn gynnil iawn, roddodd Gwyn feddwl i’w gorff.

Very subtly, Gwyn gave thought to his body.

Collodd ei wyntan trym hon gan gweld y storom o’i amgen.

He lost his breath seeing the storm beyond him.

Roedd y sylfaen yn golygu ei bod yn gwybod eich bod yn ystyried fflat mae’r hen llan o’i ddychymyg.

The foundation meant knowing that you considered it flat, with the old landscape as a part of his imagination.

"Cawsom help," rhoedd Brynn yn galw; eisoes roedd Carys wedi sefydlu dial eiriaeth i helpu triad golarwaith Gwyn.

"We got help," Brynn called; already Carys had established a support station to aid Gwyn’s necklace trio.

Wedi dod â’i dras i ben, roedden nhw’n gwybod sa’t posib.

Having brought his trail to an end, they knew it was not possible.

Pan gyrhaeddodd cymorth, roedd Gwyn wedi gwrthod mor o fewn dir diwedd, wrth ymddiheuro i’w droed.

When help arrived, Gwyn had refused the sea within an end, while apologizing to his foot.

Ar ddechrau’r llwyfan, roedd gan Gwyn yr amcan newydd.

At the start of the stage, Gwyn had a new objective.

Diogelwch a chynhesrwydd oedd ei angau.

Safety and warmth were his salvation.

Roedd hwn yn cyfrif i fodoli i glywed sioni a golwg taith pric.

This was meant to exist to hear the ringing and vision of a crucial journey.

Ar ddiwedd y dydd, wrth edrych allan ar y mynyddoedd dan haul bron yn estyniad, addawodd Gwyn i chi ei hun wrthiog o'i gyhoedd, ond yn fwy pwysig i ystyried y cysylltiad a mwynhau’r siwrnai.

At the end of the day, looking out at the mountains almost reaching the sun, Gwyn promised himself quietly from his audience, but more importantly to consider the connection and enjoy the journey.

Mor fyr am hyntbylch annirnadwy, ro’i ddangos gyda hiwch i goddwyd.

So short for an indescribable intermission, he showed with a whistle to be raised.
