I invested in a tri bike last year and I’m scheduled to do an Ironman next summer. I’m trying to work out my best options for food storage on the bike. When I’ve done previous IM races I used a cheap top tube bag which could hold up to 3 Clif bars. Now that I’ve got the tri bike (previously just used a road bike with clip-on bars) I was going to get a more aero top tube bag that can attach using bolts, but the only ones I can see appear to have very limited capacity (perhaps only a few gels). Does anyone have any suggestions or recommendations for what they use to store sufficient fuel for an IM?
My fallback is to wear a cycling jersey and store most of my food in the jersey pockets.
