What is the distance of the rides that you hope to do during the first trimester or so of your pregnancy? Guess if it's occasional, shouldn't be a big deal..?

I've never had any of the energy drinks, energy shots, etc. that this forum has discussed all along.

And I've been cycling on some long rides 50-100 kms. in a day in high humid heat. With hills/pannier weight on multiple wk. cycling tours. I just try to if there's choice, to eat whole foods or foods not too greasy/fatty. The latter is the hardest on me during a ride.

While you might have these energy drinks, etc. maybe less during pregnancy combined with some whole foods in small portions.

Best of luck. Great that you're exercising.
