is it because these people dont know your situation?ie that you have a 18month old dog...but youve only had him for 3weeks?
as a rule a springer does need free running for its own mental health,theres nothing like watching a springer working/springing/running about, HOWEVER i think you are doing the right thing at the moment,until you are sure of your recall skills!!!
well done stick to your guns!
what you could do,is put him on a long line ,you take the end of the line,but get someone to hold the dog,when you get to the end of the line,go "nuts",calling his name,patting your legs etc,get your helper to hold on tight-for a good few seconds,until the dog is REALLY focased on you,then let him go! when he gets to you & probaley knocks you flying reward him with loads of praise & titbits!!!!
jogging with him is good or maybe cycling,if you can find somewhere to cycle that has soft ground for him to run on,& dont go too fast,or too long!
good luck,youll get there!
for his first free run it may be a good idea to do it with a doggy friend that has a good recall!!!
