Course intel
Cascais 70.3: start on the coast and loop inland, just over 900 m of elevation gain, mostly short and medium climbs (high point 229 m), with bends on the descents. Late October in Portugal is comfortable; restraint on the climbs is what buys you the second half.

Speed score
Rolling terrain is where you overspend without noticing: 20 extra watts on every little rise adds up and empties your legs for the back half. Let power touch the top of the range on the small stuff and leave it there.
