Wonderful weather, happy leg even after interval training yesterday and a rush run to train station today morning. And... wham
on the way back uphill, I notice I just can't keep my HR at zone 2 at all no matter how granny gear I use... And going 2mph slower than usual. I stop and look behind and of course...
Tire is almost out of air... Found slow leak, repair... rode rest of way frustrated. 2nd flat in a week. It unfortunately takes me 30 minutes to repair this on road... (SRAM Dual drive, 20" rim with tire that just won't get on...)
Less than a year and already 3 flats on commuting...
