Unless I'm missing something, with only 72 days gone (just less than a fifth) and a lot lot more to go, publicity is not an urgency to a rider who's main need is to be allowed to quietly get on with the simple schedule of riding each day.
If there is any urgent need (funds, practical support, etc) that would best be done through already obviously involved and likely supportive communities such as this. Otherwise the likelyhood is a pressure for daily distractions to anything other than distance.
Publicity is best left till towards the end when the target is done/near done.
