Yesterday a pleasant flight towards Barco with the whole group landing there or a bit beyond.  Some, not in our group made 100km.   Today a fantastic day with easy climbs to the cloud base at around 3400m.  An easy run to Avila(55km), though a little N there low down.  We decide to land (Nigel, Ian, Hans and I) and were back for the evening flight with the others.  I imaging pilots who persisted would have done over 100km as the convergence was well marked by Cu to beyond Segovia.
