Tired so just some 100m's

Kids xmas party in work shortly so in early and at desk for 7:30 so I could grab a half hour on the erg at lunch - initially was going to do 30r20 70% but had no energy mentally as not great amount of sleep this week - been waking at 4am. So after a few minutes I stopped and thought I'd chuck some 100m's in - no structure other than trying to see what works for me - think I'm struggling on the start as only hitting 1:45 first stroke - able to hold 1:12 easily enough after third or fourth - not too bad but think I can get faster if I sort that first stroke out

On four of the 100's I had 14.7 showing only to be rounded up to 14.8! lol
