It was fun. There is a lot of technique. Hill Climbs Hill climbs are not just climbing fitness but fitness is a requirement. If you are close to others, technique becomes critical. Knowing how to use the roll of the climb to maintain your momentum is important.
Most riders slow down on steeper stretches and shift gears.
Better climbers just lean on the pedals or stand up on them to carry their momentum up the grade. Losing speed on a long climb is tough on legs because it is hard to regain that speed and it kills your legs to struggle at a slower speed. Learn to attack when the grade eases because it is easier on your legs and others will want to slow to rest. Long climbs are very mental. Don't focus on how far it is to the top.
