Orienteering 2:13:00  12.1 km (11:00 / km) +390m 9:28 / km
OMM replacement, ran with 5kg race weight pack. Congo, Mytchett E, then W, back then to E. Less than 2min errors. Stopped watch when swopping maps & rearranging pack. HR b/w 125 & 135.
Planned 16.5k & 64c, did 10.3k & 40c.
Very surprised that running with pack seemed normal if slower. Only walked where it was safer or steep as normal. Bodes well.
Fine for 75 min, at 105 min R shin hurt & achilies hurt, so followed course to water point & cutbout Windmill loop.
