Tips for your half marathon.

Start conservative

The first 5km should be at target pace or slightly slower.

Split it mentally

Think of the race as 2 runs: 15km of preparation + 6km of execution.

Respect the taper

Reduce volume in the last 2 weeks. That's when your body absorbs the training.

Trust your training

If you followed the plan, you're ready. Doubt is normal.

Simple. No surprises.
