Prior to my BibRave care package of Justin's, I had only had the Chocolate Hazelnut butter. Now I've had the chance to sample the Maple Almond Butter and classic almond butter. All three flavors are full of such rich, nutty goodness. I'll eat it on bread, pancakes, bananas and just by the spoonful. The other benefit of Justin's as opposed to some other spreads is that they are available in the small squeeze pouches. Yes this is convenient for me as a mom to just squeeze one out onto some bread and in literally 1 second I have a meal for the kids or to take a couple of pouches with us on the go. That in itself is amazing but this makes my ultra runner self even more excited. The little pouches are perfect fuels for ultras. I packed a few for my most recent 50K. They are very easy to open while on the run and squeeze the yumminess right into my mouth. As far as calories and fuel definitely a step above the gels and tastes WAY better.
A couple other Pro opinions on Justin's:
