Road/Trail Mix (Easy) 48:00 [1] 10.0 km (4:48 / km) +100m4:34 / km shoes: Adidas Tempo 8
Got a very bad 'cramp' in upper medial L gastroc while limbering up for today's hard session. Very tight to stretch so just went dead easy. Hardly noticed the calf when running, feels tighter walking. Hopefully OK tomorrow.
