## Frequently asked questions

### How many Maurten gels do I need for a marathon?

It depends on your carb target and which gel you use. At 60g/hour over 4 hours: about 10 Gel 100s or 6 Gel 160s. Mix and match with Drink Mix to reduce what you carry.

### Should I use Maurten Gel 100 or Gel 160?

Gel 160 delivers more carbs per packet (40g vs 25g), so you carry fewer. Gel 100 is easier to dose in smaller amounts. Many runners use Gel 160 for simplicity.
