A memorable 600m ride...
Yes metres, not far but...
I recently recalled, prompted by Katie's YouTube, and (less recently) re-rode my first memorable ride.
Katie's 'Why we ride'
It was only 600m but stuck because 200m was on 'the main road', Triangle Rd, first time alone outside the permitted suburban street boundary and not the adjacent private access road.
Have ridden much further, and in multiple countries, since then but it is still those sorts of milestone rides—whatever the reason—that make memories.
