Plan an even effort. Early on there are cobbles and a gentle rise to Charles Bridge, so do not push the first 3 km. Expect small ups and downs, not one big hill.
| Section | Terrain | Advice |
|---|---|---|
| km 0–5 | Old Town streets, cobbles, Čechův Bridge and Charles Bridge | Run 5–10 seconds per km slower than goal pace on the cobbles and the crowded bridge. |
| km 5–19 | City-centre roads with several bridge crossings, turning point around km 19 | Settle in at goal pace and keep your steps light on the bridges. |
| km 19–35 | City-centre roads and the river bridges on the way back | Hold steady effort; small rises will cost energy if you chase pace. |
| km 35–42.2 | Return to the centre | Use what you saved and run the last 5 km by feel. |
A guide approved by the organiser says water and food are given about every 2.5 to 3 km. Take a gel before the cobbled sections in the old town if you can, because they are harder to run while eating.
It is mostly flat with gentle climbs and some cobbled sections. Published figures for the total climb vary between sources, so expect small ups and downs rather than one big hill.
