How many km's can you do on the longest - daylight - day of the year??

The Summer Solstice this year will be on Sunday, June 21.
Sunrise here just north of Toronto will be at 5:36 and Sunset at 9:04.
Thats 15 hours - 28 minutes -4 seconds.
Your daylight time will depend on the longitude you live at; the further north the longer the amount of daylight.

I plan on riding east towards Cornwall from Sunrise to Sunset. Based on my randonneuring times 10 years ago if figure i'll be able to go up to 400km.
Anyone else interested in the challenge?

I have signed up to do the Vancouver Island Hare & Tortoise 1000km, which starts on June 20 and runs through the solstice, so I imagine that I'll be good for at least 400km on the 21st. :)

[edit: oh, just noted that distance only counts for daylight hours. In that case, I'd probably only be able to kick in about 300km for 15 hours of riding.]

do folks living in the Southern Hemisphere get special dispensation for doing the longest nighttime rides on this day?

Last year I rode 200 km on the Summer Solstice ... this year my summer solstice isn't until December 21st.
