Shadwell basin 5*1km intervals with 2min rest. Plan on making these a regular fixture again.
Pretty consistent (3:30-3:40) given little corners and loops on some of the legs, but still slowed a little over the workout. Great to get back into the speed work, but a little way to go to get back to a sub-17:30 5km (3:30m/ks)
Also, my max heartrate seems to be doing the opposite of the rule. Over the last 3 years, my max reported heartrate has increased 1bpm each year...
