I'm not a clydesdale, but I just want to suggest that gloves aren't the answer if you have numbness. All that will do is give you cushier numbness (kind of like what a padded saddle does to your butt). You have a fit issue, with too much weight on your hands for your riding style or intensity. Try saddle just a bit more back to re-balance yourself on the bike, and also try raising your bars a bit (and if you do, you will probably need to get a stem that puts the bars correspondingly farther out so you don't end up too scrunched. This way, you maintain the same overall body angles, just pivoted back a bit.
