Frequently asked questions

How many gels do I need for a marathon?

Most runners take one every 30–45 minutes after the first hour, so typically 4–6 for a marathon. Practise your plan on long runs; stomachs vary.

Should I try new kit on race day?

No. Wear shoes, socks and clothes you've done long runs in, and only use gels you've tested in training.

Where do I put gels during a race?

A running belt like a SPIbelt or FlipBelt, shorts with pockets, or pinned to your waistband.

How do I stop chafing on a marathon?

Apply anti-chafe balm to thighs, underarms, bra line and nipples before you start, and wear kit you've done a long run in.
