The former England captain, who has made various television appearances throughout the day to drum up support, is travelling between various locations across London as he takes on the challenge.
Flintoff's first record broken this morning was achieving the fastest time to drink a hot chocolate; which he did in 5.45 seconds. He also smashed the record for the most amount of likes on a Facebook page in one hour, hitting 52,719 after 60 minutes.
The 34-year-old teamed up with Steve Harmison to break a third record, when they took just 1 minute and 58.62 seconds to travel 100m in a pedalo.
After breaking the record, he said: "That was much harder than I thought it would be. It was the record that I most wanted to complete though so I'm really happy about that!
"I've got to be honest, the day did get off to a shakey start but after getting these three in the bag I'm feeling much for confident and I'm determined to finish on top!"
Among the records Flintoff has failed to break so far are a 100ft reverse bungy, a three-point turn in under 15 seconds, eating a muffin in 35 seconds and zorbing 100 metres in 30 seconds.
While he unsuccessfully attempted to wrap Holly Willoughby in newspaper in three minutes and seven seconds live on This Morning, Flintoff did manage to set a new record after kissing 40 people in just thirty seconds on Loose Women.
Piers Morgan and James Corden have been among those offering their support, encouraging Twitter users to help trend '#Freddies12'.
Highlights will be shown during the Sport Relief telethon, which takes place this Friday on BBC One.
