The marathon's avenues, short version
On the 2026 course, the start is within sight of the Victory Column and the finish is at the Brandenburg Gate, after a run across the city past many Berlin landmarks. The organizer describes it as flat: its elevation profile shows a maximum height difference of 4.3 metres (14 feet).
In early April, temperatures sit around 5 to 12 °C, with a risk of cool wind in the Tiergarten. The plan schedules a cool-weather long run in race kit.
Ten late-winter weeks
Race on April 4, 2027: the 10-week plan starts on Monday, January 25. The AI coach applies its cold rule in the first weeks, then normal paces as soon as the frost is gone.
The weekly review compares planned and completed on Garmin, tracks the training load and brings an assimilation week forward if how you feel deteriorates two weeks running.
Pacing strategy in Berlin
Instruction: first two kilometres at target pace plus 5 seconds, steady target pace afterwards, let go over the last five kilometres. On such wide avenues, run the inside line in the turns: the official course is measured at the shortest.
- Late January to February: volume, long run up to 75 minutes.
- March: threshold and half-pace blocks up to 12 km, 90-minute long run.
- Early April: taper.
The plan's "Race" session, scheduled on the watch, carries the pace range and alerts you at the first too-fast kilometre.
