Net mildly downhill, gentle rollers. Run goal pace +3 sec/mi (+2 sec/km) MAX. The crowds, downtown energy and slight downhills will tempt you. Resist. Lock onto a pack moving your pace and hide.
The climb = ~30 m / ~94 ft sustained over ~1.5 km / 1 mi. Hold effort, not pace - expect to lose 15-25 sec/km (or 20-30 sec/mi). Punchy rollers inside the park, then ~30 m / 100 ft of free downhill back out. DO NOT hammer descents - quads will write a check at km 37 / mi 23 you can't cash.
Almost dead-flat back via Eastern Pkwy. Out of the park feels weird - give it 1 km / 0.5 mi. Reset rhythm, then with 10K to go (km 32 / mi 20): if HR is sustainable, nudge 1-2 sec/km (2 sec/mi) faster. There's a small free-pace stretch at km 37 / mi 23, then a tiny bump just before the finish.
