August 12, 2021,Cwm Gwdi Loop and the Corn Du Goat Track, Brecon Beacons, Wales.

This has been a favourite hike of mine for over 40 years. Since I was in the military in the late 70/80’s. The weight package then was about 35lb. Now it’s a 20lb daypack. From Cwm Gwdi car park to the top of PYF we used to have a 50min cut off time to do this 3.5k 550m ascent leg. …

On the ridge it goes a little further in the direction of "Corn Du" and then continues downhill over …

August 7, 2024,Corn Du & Pen y Fan

Or: "The red climbs are killing me."
That's probably the sentence I said most often today.
On the first climb, the wind got stronger and the visibility got worse and worse, so that I thought: "This is going to be another zero-visibility thing."
At one point an older gentleman sat on the side of the path. I asked: "Everything okay?" …
