Half-a-hundred

Took off at 3 p.m.on my bike. Went to Inola on hwy 88 via flint road, then east into a steady head-wind (12 miles) to Chouteau on 412, then north to Pryor on 69, then west back to the house on 20.
50 and 1/2 miles according to mapmyride.
With 1 coffee stop at chouteau and a water break 10 miles from home, it took 4 hours and 10 minutes.
250 minutes for 50 miles. I've been planning on traveling at 5:30 to 6 minutes per mile (with breaks included)  and with more weight in the panniers, for a 100 mile trip, so this looks do-able.
