This was my first and third marathon. There are hills and a long stretch on Kelly Drive to Manayunk and back. The crowds are a plenty in Center City and Manayunk but you will be lonely on Kelly Drive where you will be at the end of the race. It's been chilly during the race but most people enjoy the temps. The race shirt and medal are very nice. The expo has the typical sellers. i always enjpot the Philadelphia race weekend races.
