Sunday rides had always been about 25 – 30 miles long, but weakened from wine one Friday night, I suggested a longer route. Netley to Hurst Lighthouse and back again. A route of about 55 miles except it ended up a lot more.

Breakdown + missed ferry = proper ride - Well done!
Looks like ideal fat bike territory - it would cruise over the shingle with ease plus you could have bagged some beach riding as well
