Katarina Johnson-Thompson has seen her emotions swing from the highs of success to the lows of injury despair this year.
But she is back training and ready to make her mark once more in 2015.
The Great Britain multi-eventer was forced to miss both the Commonwealth Games in Glasgow in July and the European Athletics Championships in Zurich in August with a foot injury, at a time when she was in the best form of her young life.
Still only 21, she had won world indoor silver in the pentathlon in March in Sopot and then in June, her 6682 points gave her heptathlon victory in Götzis with a score that has remained the best in the world this year.
But she has used the upset of having to watch the championships pass by this year to give her even extra motivation for what lies ahead.
In a revealing interview with bbc.co.uk, Johnson-Thompson said: 'After the Commonwealths I was refocusing and refocusing, all for the Euros and then... I was hardened to the world after that: don't expect anything unless it's actually happening.
That was the past. Now the present and the future.
She added: 'I can already feel myself putting a lot more into training than I used to at this time of year. I am a few weeks into winter training and I am still enjoying it.
'I just want to do the exact same thing I did last season, but not get injured. I wouldn't change anything. The injury was just unfortunate.'
Great Britain has some legacy at the multi-events, and just looking at the all-time national heptathlon rankings shows that.
Johnson-Thompson is third with those 6682, behind two Olympic champions – the London 2012 gold medallist Jessica Ennis-Hill, with 6955, and Sydney 2000 winner Denise Lewis, with 6831.
Ennis-Hill is set to return after giving birth to her first child in July which will add even more spice to the multi-events, both domestically and internationally.
And as Johnson-Thompson said: 'It will be good for heptathlon to have the Olympic champion back. It will be a great year.'
