Great day with a lot of speedies. Some people got a PB, congratualtions with that!  I used 2x GPS devices today. One showed a higher peak (91.64kmh), the other showed a better average. I used the one with the better average in this posting. My 6.2 was powered up nicely, but it won't go much faster then this. A 5.6 might be better in these conditions.
