ok first big 80 mile sportive in July and I was wondering if it was worth taking gels on my training runs. I recall at the TDF 2 years ago one of the sky team was penalized for dropping back and attempting to get Chris Frome a much needed gel! So are the much needed gels a benefit? If I find myself running low part way through a cycle will I get an instant (but presumably not sustained) hit from a gel If the answer is yes could you recommend what gels I should buy so that I can start carrying with me and get used to using them....
