Today's plan initially included this year's first bike ride along the Berlin Wall Trail.
Unfortunately I had a nasty flat tyre and I didn't have full trust in the tyre and the patch anymore so I decided to head home 30 km instead of doing the remaining 90.

Corpus delicti.
@encarsia where I live (Eastern England) there is a lot of flint around, a shard of this once even managed to pierce a Schwalbe Marathon (sold as "unplattbar" and advertised as being able to run over drawing pins without problems..)
@vfrmedia I ride Marathon Plus and it just happens from time to time (once or twice a year). Nonetheless after about 2 years the tyres are quite tattered _because_ they work as advertised.
@encarsia Schwalbe do to be fair make decent tyres, I've used them since about 2002 on various bikes (before which I had much more trouble with punctures) and would have ordered them for the pedelec (which I got in 2016) had this model not already been delivered with the Kenda equivalent as standard..
