I always wanted to run this race but was afraid to because of the big giant hill that used to be in it. So I thought it wouldn't be a flat enough course to get a PR but I decided to go for it. I was lucky enough to have a co worker pace me for the first half and so much crowd support. The hill was no object for my motivation because I was on pace to PR! There was so many people out on MLK drive and though I was cold and took a while to warm up, it was worth it I had gotten a 5 minute half PR!! As with most Philly races, the parking and getting to the start is the most difficult part. if you can get someone to drop you off in the morning that is the best way because streets are closed and parking is hard to find. If you're able to public transportation and walk to the start that its a good options as well. There was about 3 decent size hills but the first half is basically all flat and in the city, (watch for potholes) and your GPS might not work and be all wonky and throwing off your mile spilts I wasn't sure what pace I was running! Even if you think hilly course are good for you, I would highly suggest you to just try Love Run Philly- you won't regret it!
