Personal Notes

AJ Bell Great North Run Plan (Week 8/8)

0.75mi warm up at a conversational pace (no faster than 13:10/mi), keeping things easy for the majority. Within the warm up do 4 x 100m fast 'strides' aiming for around 11:20/mi. 60s walking rest

4 reps of:
• 0.5mi at 12:50/mi, this is your target Half Marathon pace, 90s walking rest

0.5mi cool down at a conversational pace (or slower!) with Runna. AJ Bell Great North Run Plan (Week 8/8)
