Hmmm....I see.....  Are the first 3 - 5 also on tarmac?  Do you carry a small tire pump? Seems the only thing to do is let some air out when you hit the woods, then pause for a break when you reach the asphalt again and pump 'em back up.  I have a pretty good little pump made by Topeak, and just a few puffs is all it takes to get the tires nice and firm.  Like the pit crew at a NASCAR race, I can get the tires prepped speedy-quick.

So, sorry to say, but the only thing to do is find a quiet shady spot by a stream, fortify yourself with a glass of chilled chardonnay from your picnic hamper, dip your toes in the water, sniff the flowers, and then pump away like a crazy man.
