Wot Dave said.
As far as I can see, members post TRs about all manner of walks - long or short, lowland or mountain, coast or country, mulri-day or just an afternoon stroll.
I would say that if the report is interesting, informative and engagingly written it doesn't matter how long or short it is, nor where the walk took place.
Yes, many people like to see photos but - to me at least - they are the icing on the cake, not the cake itself.
