I went to wash my bike to get ready for the race and put on my new bash guard. Ended up changing the rear shifter cable 'cause the housing pulled out of the shifter and was messed up, saw a wicked thorn in my back tire so i pulled it and found out all the sealant dried up, so i pulled the tire off to clean and reseal it. I thought I may as well do the front while i'm at 'cause it's tubed. Found out the rim tape was bad so I ran to Healthy for that and a shifter cable. when i was all done, i found out i put the front tire on backwards. I ended up spending about 5 or 6 hours working on my bike.
