Technically I spent extra 30 minutes to find a grave of April Jones, to whom I have dedicated my challenge. However, excluding this time, I spent 18h 24mins on challenge itself, which is 4h less than year ago.
18 hours and 24 minutes
The Welsh Three Peaks Challenge involves climbing Snowdon, Cadair Idris and Pen y Fan in the same day, either over 24 or 12 hours.
