Intervals.icu

What the night throws at you

Typical sessions

Eight to twelve hours in the saddle at an easy pace, so aerobic durability and contact-point comfort decide your night

Riding unlit lanes in the dark, where good lights and full-night battery matter more than fitness

A cold, sleepy low around 2 to 4am when rural Suffolk can drop into single digits even in July

Fuelling yourself for the long haul, self-supported, with no guaranteed food stops on route

What your weeks look like

Typical sessions

A progressive long ride building from 2 up to 6hr+ of easy Z2 on flat, rolling terrain

A fuelling-rehearsal ride of 5 to 6hr holding 40 to 70g of carbs an hour on your exact race food

Dark rides of 2 to 3hr after nightfall on the actual lights you will use, to build night confidence

A full dress rehearsal in the exact kit and lights, proving warmth and battery before the night that counts

Not a generic schedule

Typical sessions

Built from your current fitness and the time you actually have

Adapts every week as Beina learns how you respond
