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.
