The dry dock at Suomenlinna, a quiet and calm place this evening.
Drumsö 9k @ 5:22/km
Sunday slow 21k
This is roughly the outer first loop of the Helsinki city marathon (2009 route map). The second loop is slightly shorter (see here)
With tired legs there were no problems keeping the pace slow 🙂 Getting used to new shoes which almost resulted in some blisters...
PIKANTO nr 3 sailing
Got a chance to sail PIKANTO hull nr 3 today in Turku. After a bit of servo-programming to get the travel on the HiTec winch dialled in right it was on with the deck patches and onto the water. Turns out the balance is pretty darn good as we had gusty nr1 rig weather today and the boat behaved very well in both the lighter and the stronger breeze. I missed two races because of a flat boat battery - the HiTec arm-winches demand a little more attention to batteries, wires, and connectors, since they draw quite a bit of current. After two summers of sailing a Noux with a fairly narrow 85mm chord fin the Bantock-style large-area fin (120mm chord at the root, tapering to around 70mm) feels easy to sail and difficult to stall. A bit more rudder travel, some more rig tuning, and lots of sailing routine and I feel this will become a great boat to sail.
Two non-PIKANTO pictures: In the middle of racing this dude pulls up with his muscle-motor-boat and starts to load it up with diesel. ZOMG: almost 400 liters costing more than 500 euros!
Our starting sequence was played from a USB-stick, no more trouble with wobble of the player causing the CD to jump and interrupting the sequence.
8k at 5:14 pace
Through the Finnish running forum I found a Jim2's running page which seems to have a lot of useful information. The Ultimate Speed Workout is... simply a 10k race.
So the idea was to warm up for 1k, and then run properly for 10k at around 5:20 pace, which is slightly faster than last weekends Forssa half-marathon pace of 5:32/km. That was probably a bit optimistic, as it felt like serious work up to around 5k, after which some kind of runners-high sets in, calves, legs and everything relax and settle in on the pace while kilometers 6, 7, and 8 fly by much faster than the planned 5:20. After that it's a struggle again for km 9, and I decided 8 fast kilometers were enough...
WordPress 3.0
I've upgraded to the latest WordPress 3.0
The black theme looks too black for summer, must find something better.
Hopefully some PIKANTO-building posts as well as new features and ideas for opencamlib (which nobody reads?) in store for July.
Stay tuned.

Forssa half-marathon
I was a bit too far back in the start, and had to criss-cross among slower starters for at least the first 3 km. A strong side/aft wind made the first few kilometers easy downwind 'sailing', and luckily the route took a more protected less windy road after the turn at 10 km. After around 13km when it was windy again, now a side/head-wind, I slipstreamed in tour-de-france-style in the wake of a group of runners to avoid the worst wind. This course is very flat and fast, and I caught up with the 2-hour pace-runners(dressed in black tuxedos!) somewhere between 19 and 20 km.

While driving home through Perniö I saw some serious long distance runners taking part in a 100 km race. These people do 20 laps on a 5 km course, some in under 8 hours...
