Wind speed 20mph,soft gravel from rain the night before = 9 mph low gear 145 heart rate great TRANS IOWA training ride.I rode from my house north about 3 mi then went west into the wind about 4mi where there is a gravel that goes straight into Ames, just south of Ames went east with the wind. Then found a gravel south, after about 3mi south a German Shephard came after me, now regularly I’d crap my pants,but Mark told me usually you can outrun and outlast a dog. So I put the hammer down luckily a side tailwind pushed my rig up to about 23mph and the dog fell off after about 1/4 mile.Looking down at the HR monitor I saw 172, now thats interval training,so I finished the ride after about 2 1/2 hours and thought to myself only around 28 more for the TRANS IOWA experience.Im still learning about how my bike set up may be wrong but I can fix that.
