You can make the journey alone - but that's not much fun - or with friends.
Several of our group, myself (back) Chris H (front left) Angus (in the middle perusing his itinerary) Jane P (looking over A's shoulder) and Neil P (hidden) + my youngest son, Luke (front right - oldest son, Adam is the photographer) went down to the Monmouth stop, just inside Wales to cheer the avid cyclists on their way by sharing an evening meal with them and bringing them supplies of home-made cake to keep their energy levels up!
As a writer, you can struggle on alone feeling a little depressed and rejected or you can from time to time meet up in writing groups and workshops. Like the cyclists this can spur us on to keep writing by the mutual support and encouragement. The treats, be they home-made cakes or glasses of wine or bars of chocolate etc. can also be an incentive to keep going. For instances, if we've had a good day of writing for a number of hours and produced some good copy, either adding to a novel, a short story or a poem, a small treat is a good reward to encourage us and spur us on to do the same again. Just like the cyclists.
Like the Land's End to John O' Groat's cycle ride, writing it a challenge. It's not just something you do one day and then do something else the next. As the bike ride challenge, you have to continue, getting up each day and keeping on going whether you want to or not. Hopefully, in both cases it will be worth it in the end for the sense of achievement you'll experience.
