With four days remaining before the Ohme 30 K Road Race this coming Sunday I did some core exercise and stretching. I do a number of core exercises depending on my mood, but tonight I did handstands. I started the first round for 50 seconds. And from the second round on I cut the duration down to 30 seconds and did six more rounds with a rest for 30 to 60 seconds in between. A handstand hits core, shoulders, traps, and triceps, all of which aren't that actively used except core and shoulders, so the negative effect on the race performance is minimal.
Tomorrow I might jog for a while if I'm in a mood. If I'm not, I'll just stay home and relax. At this stage nothing will really improve my physical capacity so dramatically.
