For an elite athlete who has represented Great Britain at the Olympic Games, running the Boston Marathon in two hours and 43 minutes may not seem like much of an achievement.
After all, that’s about 20 minutes slower than your personal best.
But Calli Hauger-Thackery did it on Monday when she was 22 weeks pregnant, and she points to the race as an “incredible” and “most meaningful” moment in her career.
The 33-year-old, from Sheffield, ran the same race last year and finished sixth in a time of 2:22:38, and knew she would face a tougher task this year.
“I’m grateful to have got through that today. 26.2 miles is no easy feat and I’m very grateful to have done it so far in the pregnancy,” she told BBC Sport.
Like any marathon runner, he encountered some setbacks along the way. She had to be treated for a trapped nerve in her glute at mile five and again at mile 11.
“I had to run to the medical tent because I had this trapped nerve.
“Honestly, I couldn’t even lift my right leg properly. I was dragging it and I thought, oh no, this is not good and we’re at mile five. I thought, ‘guys, is there anything you can do?’
“Luckily they were brilliant and were able to publish it.
“I had two small stops, like when you’re pregnant, you need them more than ever, but this was all before mile 13.
“The second half felt perfect, like I was in tune with my body. I felt like a million dollars. I was like, okay, we’re actually doing this. Because there were so many times before mile 13, which is the halfway point, I didn’t think I was going to end up in that race.”
