quayside to newburn to gibside to newburn to the cycle hub

We are setting off from the pitcher and piano pub on newcastle quayside at 8.30am prompt, heading along the river on the south side to newburn to join the skyride to gibside national trust for a cuppa and cake (optional) before returning to newburn and then back to the quayside on the north side for a change of scenery. Total distance will be around 40ish miles on mostly cycle tracks with a little road use. You'll be lead by a skyride leader and the first 10ish miles will be a steady 10ish mph before settling into a possible slower pace to gibside and back (average between 7 and 10mph) and at all times we travel as a group not leaving anybody behind apart from mechanical issues that cannot be helped with. Bring a puncture repair kit, pump, levers and possibly a spare tube plus some cash of you plan to enjoy gibsides catering. Do consider this is 40 miles which is manageable but challenging.
