On my last half, switching to 2:1 glucose:fructose gels and taking tiny sips every 10 minutes kept my stomach happy — think espresso shots, not milkshakes — and I stick to the “gel + water, never alone” rule. Small caveat: on hotter days I delay the first gel to 25–30 min and add a bit of sodium to the bottle to prevent slosh.

I started getting faster callbacks for remote cardiology NP roles after I moved my telehealth platforms (Epic/Zoom) and state licenses to the very top of my resume. > telehealth opportunities with Get It Recruit — Transportation and Get It — Healthcare. Ideal for those looking to work from home while — true, but they vanish quickly, so set 24-hour alerts and try to apply within an hour.

Found I could push about 90 g/hr only after pre-mixing gels into a 250 ml soft flask at about 8% and using a 7‑min watch buzz — keeps the “multiple transporters” happy and my gut calm. Small caveat: space caffeine gels and chase with plain water. Quick why behind it: https://www.mysportscience.com/post/multiple-transportable-carbohydrates.

Cold gels turn to glue for me, , so I stash a soft flask in a chest pocket to warm it and draw four tick marks to finish one mark every 5K instead of chasing a timer. That made the whole “carbohydrate transporters” thing work for me — mixed-carb gels go down smoother and my stomach stays calmer. If the course markers are sparse I just sip at every other aid station, @h_grace92.
