5 min @ ~8-8:15 min/miles
Start with 5 minutes comfortable and then stop and let the HR drop for two minutes. You will find that this will recharge your brain and body, especially if your legs were feeling heavy after the bike workout.
Then do 3 x 5 minutes steady pace w/ good form w/ 30-60 sec walk in between. Make your last 5 minutes your best. Then cool down as needed.
