Well today I completed my first double century! My husband and I did the Davis Double Century (his 12th time) on the tandem in 14 1/2 hours (13 1/2 hours on the bike). I am SORE and may be missing a little skin on my lady bits (despite copious re-application of chamois cream), but I somehow did it. We also got a lot of compliments/thanks for our "super strong" pulls (which my husband felt compelled to offer, ALL DAY, hence my being wiped out). Next time, when I'm actually *in shape*, we will probably REALLY kick a**!
