I always always get beaten by girls at tennis. even if I try real hard. its sad. Either they can't play at all or they just serve me my own ass.
Rob and I got dropped by this female person on the donut ride once. There was a brutal brutal headwind and we were going up hill and it was all that I could do to just hold onto her wheel. There was no chance I could have taken the lead without forcing her to slow down. Eventually we couldn't keep up at all and she just kept spinning into the distance. I needed to stop and eat a few granola bars after that. We decided to cut our losses and just turn around at that point. But damn, full respect to whomever we were wheelsucking.
edit: oh yeah, alleycats would level the playing field a bit due to all the possible variables. Women can use their inuition that I keep hearing about to predict if there will be cross traffic at red lights so they can bomb them at a speed 'strong enough for a woman' (strong!)
