what the hell are you trying to tell this guy?? let me just say that i have had a stress fracture in my left tibia and i did run a race on it. not only did my times suck the world's largest shit, but my leg hurt like a f***er after that race. i tried taping it, it didn't work. i spent the next two and a half MONTHS off running and doing physical therapy. not only does that cost a shitload of money (which thank god my insurance paid for) but it sucked up a lot of my time and made me fatter and slower. only now am i recovering.. i have about another month left before i reach my previous condition. trust me. it is NOT worth it. i was too eager to try running on my stress fracture during my recovery so it never really got a chance to heal quickly.
just take care of your leg. my suggestion is to take care of it as quickly as possible so that you can return to recovery ASAP. sleep a lot, drink a lot of water, eat healthy (lots of milk, etc), and cross train. however, don't bike in the beginning. ease yourself from aqua-running to swimming to biking. swimming may irritate your foot because of the kicking, but you can try swimming with your arms only (just build up your upper body). don't lift weights too soon either. keep pressure off! and don't forget to ice. my leg was pretty inflamed the whole time. anyways, luck with your sf, let us know how it goes.
