Starting Blocks

The start is divided into 8 blocks according to the personal best times submitted. The letter on the race number shows the block.
Runners who are participating in their first marathon will be in the last block like me.

Start is 9:15 a.m. Runners and Power-Walkers (no Nordic Walking) Time limit: 6.15 hours.

There will be three starting waves (in 10 minute intervals) and eight starting blocks.
