Yes, I would still train and compete horses with an IV. When I was in college/grad school, I still attended classes and carried on as usual, just making sure I got plenty of rest. My doc wasnt thrilled with the whole riding with an IV thing though, cant imagine why! heheh, about 6 years ago, my hubby and eldest daughter had the flu, he was too sick to watch the baby. My IV infiltrated at 1 in the AM....I ended up packing our 4 month old into her carrier and trotting into the ER to have the line replaced, which of course took about 4 hours since I am a hard stick. Youngest daughter was/is a gem. I rocked her and fed her with one arm as they tried to get a line into the other! You do what you have to. Two thumbs up for those IV balls!
