How many gels for a marathon? Roughly one every 30 to 40 minutes after the first 40 minutes. Finishing under 3:30: about 6 gels. Finishing under 4:30: about 7 to 8 gels. Over 4:30: about 8 to 9 gels. Plan to the carbs per hour on the label. Practise it on your last long run, and don't try a new gel on race day. The Taster Pack is the easy way to test.
