My very first marathon was the OD Marathon in 2012. I have trained very hard for it and was very excited to run it. And than I got sick that very week. A day before the marathon I did my 2 mile shakeout run while running a fever, and I thought I was going to pass out. Not looking good. So I medicated, hydrated and the next morning I felt OK. I took some extra medicine and the first 10-12 miles went well. I was running at a good pace. That is when the nightmare scenario occurred. Around mile 13 I think my fever returned and I was bonking hard. Around mile 15 my IT band flamed up with sharp pains shooting through my knee. I still finished with the combination of walking/running but it was awful, painful and not pleasant at all.
