Questions about the Stockholm Marathon

How hilly is the Stockholm Marathon?

About 195 m of climbing and 196 m of descent – mostly flat. 88 % of the course is within ±2 %, and none of it is steeper than 6 %. Six climbs of 10 m or more; the biggest gains 25 m from km 19.5 to 22.2 (0.9 % on average).

How much will the conditions slow me down?

It depends on your pace, the course and the weather on the day. RaceDayCast adds up the effect of hills, wind (including shelter from buildings), heat and running in a group – kilometre by kilometre – and shows how much each of them costs or gives you. Choose your goal time to see your own plan.

When can I see the race-day forecast?

The forecast from MET Norway is available about 9 days before the race, and on race day we switch to observed weather as the hours pass. Until then the plan uses the typical weather for the date.

What pace should I run to reach my goal time?

Not the same pace all the way. Run an even effort: a little slower uphill and into the wind, a little faster downhill and with the wind behind you. Your RaceDayCast plan gives you the split for every kilometre or mile.
