The course

The route

42.195km point-to-point from Shinjuku to Tokyo Station on closed central-city streets. Net-downhill with only ~40m of cumulative climbing and no meaningful rise anywhere on the loop, it is a true flat, fast course.

Intervals.icu

What Tokyo throws at you

Typical sessions

42.195km on flat, fast roads with no hill to force you to ease off and none to recover on

A generous 7-hour cutoff, but still a full marathon effort of roughly two to seven hours

The wall at around 30km, the only real 'hill' on the course, arriving with no warning terrain

Wide, exposed central-Tokyo avenues where wind is the main variable to shelter from

What your weeks look like

Typical sessions

Marathon-pace long runs up to 35km with 15-20km locked to exact goal pace, fuelled exactly as you will on race day

Long tempo of 40-60 minutes continuous at marathon pace to groove the precise rhythm you'll hold

Progressive long runs finishing the last 8-10km at marathon pace, rehearsing the negative split a flat course rewards

A midweek medium-long run of 14-18km easy to build volume without the cost of a full long run

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

Syncs your sessions straight to Garmin and Wahoo

One clear next session, never a wall of spreadsheet
