I change my program and go directly to Lisbon to avoid the overcrowding of this weekend of good weather... and the prohibitive prices towards Cascais !
I’ll get to the Alentejo a bit quicker.
On the cut the gradients look reasonable. In fact it depends on the type of road : all the first part are very small secondary roads and the slopes are steep, my meter often shows 12%. The highest hill is a national road, the slopes are smoothed out and we are on 7% max.
Otherwise, nothing too special to say about the route : except for the slightly steep slopes, it was a pleasant ride overall. A return to Lisbon that lasts several kilometres, but in the city there are real cycle paths with traffic lights for bikes... that you should respect !
