I feel you on the Monday morning blues… although my situation is somewhat different. I just got my first road bike about 2 weeks ago and went to fill up my tires this morning, but managed to completely flatten the first one and then couldn't figure out how to get the pump head to seal on the valve properly. It just kept hissing and losing pressure.
After 20 minutes of looking on the internet and desperately trying to get the tire filled and getting entirely too frustrated by the situation, I had to concede that I didn't know what to do. I was thinking of going to a bike shop down the street for help, but lots of the bike shops here are closed on Mondays. I work with people who know about bikes though, so I put the bike in the car and took it to work with me.
The good news is that I learned that the valve stems on my tubes are too short to be able to make fitting my pump head on very easily; I need to go back to my bike shop and ask them to replace the tubes with ones with longer valves. The bad news is that I broke my bike-to-work-every-day-in-May streak (although I will go home today and make up for it now that my tires have air in them again, thanks to my work friends). The other bad news is that in filling up the second tire I managed to clock myself in the knuckle with the pump head lock as I was removing it, and now my right index finger is swollen and sore.
UGH. I just wanted to bike to work, but noooo…
OK, sorry to hijack your thread. I just had to get that vent out of my system. I hate it when my attempts at exercise and working toward fitness goals are foiled; it is just EXTREMELY frustrating.
